Abstract

Non-Mendelian inheritance was revealed for the "heat-sensitivity" character of the poikilothermic insect Drosophila melanogaster. Genetic analyses were performed on heat-sensitive (S, S(1)) strains, derived through indirect selection, and on stocks constructed through extensive chromosomal and cytoplasmic substitutions between strains obtained from two replicate cage populations. The populations were kept for about 7 years under different temperatures (14 degrees -25 degrees ) and exhibited different survival. We conclude that the character studied is quantitative, responds to selection pressure and is transmitted through the maternal cytoplasm, while nuclear genes modify its expression.

摘要

非孟德尔遗传被揭示为变温昆虫果蝇的“热敏感性”特征。对通过间接选择获得的热敏感(S,S(1))菌株以及通过在来自两个重复笼种群的菌株之间进行广泛的染色体和细胞质替换构建的品系进行了遗传分析。这些种群在不同的温度(14 度-25 度)下保存了大约 7 年,并表现出不同的存活率。我们得出的结论是,所研究的特征是定量的,对选择压力有反应,并通过母细胞质传递,而核基因修饰其表达。
