  • A genome contains all genetic information of an organism. Within a specific species, unique traits appear for each individual, which can be identified by analyzing nucleotide sequences. Many Genome-Wide Associations Studies have been carried out to find genetic associations and cause of diseases from slightly different base among the individuals. It is important to identify occurrence of slight variations for polymorphisms of individuals. In this paper, we introduce an analysis and visualization tool for specific variation pattern identification of polymorphisms in nucleotide sequences and show the validity of the tool by applying it to analyzing nucleotide sequences of subcultured pOka strain of varicella-zoster virus. The tool is expected to help efficiently explore allele frequency variations and genetic factors within a species.

  • Four polymorphic allozymes were used for genetic analysis of overwintering populations of field diamondback moth, Plutella xylostella (Linne). Different allele frequencies were found among three local populations of Andong, Youngchon, and Yangsan in all loci. Two allozyme loci (acid phosphatase and phosphoglucomutase) showed significant deviation from Hardy-Weinberg equilibrium in allele frequencies among these populations. Estimated Nei's genetic distance varied from 0.0151 between Yangsan and Youngchon to 0.0877 between Andong and Youngchon. Compared with the previous genetic distances in this moth, a little higher genetic differentiation among these overwintering populations suggests that there would be a specific genetic bottleneck in each local population during overwintering period.

  • Cytogenetic analysis plays an important role in examinations of a variety of human disorders. Over the years, cytogenetic analysis has evolved to a great extent and become a part of routine laboratory testing; the analysis provides significant diagnostic and prognostic results for human diseases. Microarray in conjunction with molecular cytogenetics and conventional chromosome analysis has transformed the outcomes of clinical cytogenetics. The advantages of microarray technologies have become obvious to the medical and laboratory community involved in genetic diagnosis, resulting in greatly improved visualization and validation capabilities. This article reviews how the field is moving away from conventional cytogenetics towards molecular approaches for the identification of pathogenic genomic imbalances and discusses practical considerations for the routine implementation of these technologies in genetic diagnosis.

  • Heritability of heading date, maturing date and culm length were high and the year variation was relatively low. Yield components were considerably low in heritability due to large year variation. Direct effects of number of spikes/$m^2$ and 1, 000 grain weight to yield were high. For improved selection efficiency, at least three years continuous evaluation of experiments would be desired.

  • Isozyme and AFLP analyses were examined to estimate the utilities of them as a genetic marker. The utilities were evaluated by genetic divergence and relationships among the four distinct abalone species; Haliotis discus hannai collected from northeast coast of Japan and Yellow-Sea coast of China, H. rufescens collected from west coast of USA, H rubra collected from southeast coast of Australia and H midae collected from Cape Town of South Africa. Isozyme and AFLP analyses showed a clear genetic divergence between every pair of species. Genetic relationships among the low species estimated by isozyme and AFLP analyses reflected to geographical distribution and morphological characteristics. In conclusion, Isozyme and AFLP analyses are suitable genetic markers far estimates of genetic divergence and relationship among abalone species.
