한성계통의 전견중, 견층중, 견층비율에 대한 성차
Sexual Differences of Cocoon weight, Cocoon Shell Weight, and Cocoon Shell Percentage in the Sex- limited Silkworm Strains, Bombyx mori L.,
초록
한성반문 및 한성란색 계통잠에 있어서 전좌염색체로 인한 생리적 결함이 전견중, 견층중 및 견층비율에 미치는 영향을 이들에 관한 성차를 지표로 하여 검토한 결과, 한성 및 비한성 계통견의 전견중의 성차 평균치는 각각 127%, 129%, 견층중의 성차는 각각 107%, 110%, 견층비율의 성차는 공히 85%였다. 이상의 결과에서 한성반문 및 한성 난색계통잠은 전견중, 견층중, 견층비율 등의 실용형질에 관한 한 전좌된 염색체편에 기인하는 생리적 결함은 극히 미소한 것으로 생각된다.
Using sexual differences between female and male as the indication of the degree of the physiological distrubance in the sex-limited larval marking strains or sex-limited egg colour strains, it was investigated whether the physiological distrubance caused y the translocated autosome fragment on the W-sex determination chromosome, have an effect on expression of the three quantitative characters; cocoon weight, cocoon shell weight, and cocoon shell percentage in the female silkworm. The mean values of the ratios of female to male the above two experimental groups were 127%, 107%, 85%, in cocoon shell weight, and cocoon shell percentage, respectively. On the other hand, those from the three normal stains, namely the basic stock strains, white egg strains, and hybrids were 129% for cocoon weight, 110% for cocoon shell weight, and 85% for cocoon shell percentage, respectively. From the results, it comes to the conclusion that the translocated autosome fragment on the W-chromosome has no influences on the expression of the quantitative characters of the female silkworm because sexual differences of the sex-limited strains were very similar to those of the three normal strains.
