容器大小对不同基因型果蝇发生量影响的遗传分析

果蝇发生量是数量性状,选用野生型、檀黑体、残翅和白眼四种不同基因型的果蝇,设计25种不同的杂交组合,并将其培养在不同大小的容器内,统计各种组合的子代果蝇发生量。经方差分析,结果表明:环境(不同容器大小)对果蝇的发生量影响最大。不同基因型以及基因型与环境的互作对果蝇发生量的影响在不同的杂交组合中也达到极显著差异或显著差异。说明果蝇的发生量是由基因型和环境交互作用的结果。

Genetic Analysis on the Influence of Container Capacity to Reproduction in Various Genotypes of Fruit Fly

Reproduction of fruit fly is a quantitative genotype.To select the wild type,ebony,vestigial and white eyes of D.melanogaster,we designed twenty-five kinds of hybridized combinations,and cultivated them into various vessel,statisticed the quantity of the constituted offspring of the fruit flies.Using analysis of variance,the conclusions show that the space of environment is the major factor to influence the reproduction of fruit fly.The influence of different genotypes and interaction between genotypes and environments to the fruit fly reproduction in hybridized combinations appears extremely significant difference or significant difference.It indicated that the quantitative character is the result of the interaction of genotype and environment.
