Single nucleotide polymorphisms (SNPs) are widely acknowledged as the marker of choice for many genetic and genomic applications because they show co-dominant inheritance, are highly abundant across genomes and are suitable for high-throughput genotyping. Here we evaluated the applicability of SNP markers developed from Crassostrea gigas and C. virginica expressed sequence tags (ESTs) in closely related Crassostrea and Ostrea species. A total of 213 putative interspecific level SNPs were identified from re-sequencing data in six amplicons, yielding on average of one interspecific level SNP per seven bp. High polymorphism levels were observed and the high success rate of transferability show that genic EST-derived SNP markers provide an efficient method for rapid marker development and SNP discovery in closely related oyster species. The six EST-SNP markers identified here will provide useful molecular tools for addressing questions in molecular ecology and evolution studies including for stock analysis (pedigree monitoring) in related oyster taxa.

Information sources about Mongolian pigtail of 13-14C are relatively rich. But it was difficult to estimate the shape of the pigtail in detail with the descriptions in historical writing or travel books only, and paintings were neither enough to observe the beautiful shape of the pigtail closely on the whole because the portrayed characters were always wearing their hats. However, the authors could trace the detailed shape of the pigtail of 13-14C through close investigation into Mongolian stone statue of the period. In conclusion, the authors performed a comparative study by historically comparing the historical writings, archeological materials, ethnological materials and figurative arts featuring medieval Mongolian pigtail. And the authors paid careful attention to the meaning of those materials to the hairdo history. Historically nothern minority races have become assimilated with surrounding races in language, culture and customs through long economical and cultural exchange, and today their national traits gradually fade away by globalization. But each minority race still stands independently and maintain its own traditional culture. only recently began the study by Korean researchers on Mongolian pigtail, and there is still much to be discussed in ethnological issues such as racial pedigree.

The aim of this study was to construct a correct pedigree of miniature horses (MH). The sex of MH was detected by PCR amplification of the sex determining region of the Y chromosome gene (SRY) prior to parentage testing. Ten random MH samples for parentage testing were genotyped by using 16 micro satellite markers. Since the SRY band (430 bp) was detected in horses No.1, 2, 6, 7, 8, 9, 10, these are male. However, the DNA segment was not identified in horses No.3, 4, and 5, which therefore are female. After genotyping, parentage testing was performed according to Mendelian fashion and International Society for Animal Genetics (ISAG) guideline. Of the 10 MH, 3 were qualified by the compatibility of 16 markers according to Mendelian fashion in the present DNA typing for parentage verification. These results can provide basic information for developing parentage verification and an individual identification system in MH.

Purpose: The purpose of this descriptive, cross-sectional study was to examine Korean undergraduate nursing students' perceived knowledge and attitudes toward genetics. Nursing competencies for genetics among nursing students were also assessed. Methods: Two hundred eighty-six Korean junior and senior undergraduate nursing students who went through their clinical practicum completed a packet of self-report questionnaires exploring opinions about the integration of genetics into the nursing curriculum, as well as their perceived knowledge, attitudes, and nursing competencies toward genetics. Collected data were analyzed using descriptive statistics, t-test, one-way ANOVA. Results: Overall, Korean undergraduate nursing students reported limited genetic knowledge, but most of them were comfortable with drawing pedigree. In general, nursing students were competent in providing genetic nursing. Their genetic nursing competencies were significantly different depending on the level of general understanding of genetics. There was no significant difference between juniors and seniors regarding knowledge, attitudes, and competencies toward genetics. More than 60% of nursing students reported the need for genetic nursing, and the majority considered lectures to be the most effective method to learn genetic knowledge. Conclusion: It is imperative to integrate genetics into nursing curriculum in order to improve nursing students' genetic nursing competencies as well as genetic knowledge.

A pedigree file of 4,628 records of Muzaffarnagari sheep, maintained at Central Institute for Research on Goats (CIRG), Makhdoom, was used to calculate the inbreeding coefficient of the flock. The flock had been closed for about 25 years (1978 to 2002). The investigation was aimed to study the effects of inbreeding on survivability of lambs. The cumulative survivability of lambs i.e., lambs survived up to 3, 7 and 15 days, 1, 2, 3, 6, 9 and 12 months after birth was considered for the study. The average level of inbreeding of lambs was 1.60%, ranging from 0 to 26.4%. The average inbreeding coefficient of dam over the periods was 1.00% and it ranged from 0 to 25.0%. Significant (p<0.05) adverse effect of lamb's inbreeding was observed on survivability of lambs at all ages except up to 3 and 7 days after birth. On an average, 1% increase in individual inbreeding coefficient should reduce the 0.31, 0.34, 0.32, 0.31, 0.33, 0.44 and 0.49 percent lamb survival up to the age of 15 day and 1, 2, 3, 6, 9 and 12 months, respectively. Ewes inbreeding had non-significant effects on lamb survival at all ages.

Currently, boars selected for commercial use as AI sires are evaluated on grow-finish performance and carcass characteristics. If AI sires were also evaluated and selected on semen production, it may be possible to reduce the number of boars required to service sows, thereby improving the productivity and profitability of the boar stud. The objective of this study was to estimate genetic correlations between production and semen traits in the boar: average daily gain (ADG), backfat thickness (BF) and muscle depth (MD) as production traits, and total sperm cells (TSC), total concentration (TC), volume collected (SV), number of extended doses (ND), and acceptance rate of ejaculates (AR) as semen traits. Semen collection records and performance data for 843 boars and two generations of pedigree data were provided by Smithfield Premium Genetics. Backfat thickness and MD were measured by real-time ultrasound. Genetic parameters were estimated from five four-trait and one five-trait animal models using MTDFREML. Average heritability estimates were 0.39 for ADG, 0.32 for BF, 0.15 for MD, and repeatability estimates were 0.38 for SV, 0.37 for TSC, 0.09 for TC, 0.39 for ND, and 0.16 for AR. Semen traits showed a strong negative genetic correlation with MD and positive genetic correlation with BF. Genetic correlations between semen traits and ADG were low. Therefore, current AI boar selection practices may be having a detrimental effect on semen production.

Purpose: This study was performed to evaluate Korean nurses' knowledge about hereditary colorectal cancer (HCRC). Methods: A modified 15-item HCRC knowledge questionnaire was developed based on previous research. One hundred and forty-eight nurses have completed the questionnaire from February to April, 2011. Results: The average score of nurses' knowledge was $11.25{\pm}1.54$. Ninety-seven percent of nurses knew about colonoscopy check up schedule and family pedigree. However, only 20% of nurses knew about the rate of passing on mutation genes to offspring and risk of developing CRC among carriers. Only 13.5% of nurses had previous genetic education experiences. Working in oncology units, taking care of CRC patients, and participating in genetic education were not associated with nurses' HCRC knowledge. Conclusion: Various factors influence nurses' knowledge about HCRC. Repeated study with larger national sample of nurses is recommended to identify the factors affecting nurses' knowledge level in order to develop efficient genetic education programs for HCRC patients and their families by nurses.

The object of this study was to evaluate the possibility and incidence of innate pacer in Jeju raceresource. This peculiar gait occurs naturally in some foreign breeds. To author's knowledge, this is the first report of innate pacers on the Korean native horse. In order to determine the incidence of pacer in Jeju Ponies and Jeju Pony crossbreds, gait analysis and pedigree check were performed at the Let's Run Park Jeju (total 547 ponies and pony crossbred racers) in 2013. Results of this study showed that 16 (8.1%) of the 198 examined Jeju Ponies. However, 349 Jeju Pony crossbreds had no innate pacers. Of the 16 Jeju Pony pacers, 11 males (68.8%) and 5 females (31.2%) are included in the present study. In conclusion, only the Jeju Pony was innate pacers like other foreign breeds. The authors suspect that the causes of the difference of the breeds were origin of the pony and genetic differences.

Seveval Chinese and Japanese varieties with good characters were used in the breeding. After 5 years (15 generations), a pair of robust and high quality silkworm variety with NPV resistance was bred by means of a combination of crossing and pedigree selection complemented by the selection of NPV resistance. The variety was identified jointly nationwide in 2003 and 2004, and appraised by National Mulberry and Silkworm Appraising Committee. Results are as follows: its cocooning rate is over 93%, shell rate 23-25%, filament length 1200-1300 meters, reelability 75-88%, Length of non-broken cocoon filament 900-1100 meters, raw silk rate 17-19%, neatness 95-97 points, and cocoon crop, cocoon shell weight and raw silk weight per 10000 larvae is higher than those of the control variety by 7-10%, 14-19% and 14-18%, respectively. The variety is not only robust, resistant to high temperature and NPV, easy to rear, uniform in hatching, molting and maturing, but also lays more eggs, and its fecundity is high. It is suitable to rear in the Yangtze River Basin, the Yellow River basin and the Pearl River basin of China.
