Which one of the following examples could serve as an example to illustrate what is meant by "norm of reaction"?AnswerIn some reptiles, sex-type is determined by the egg-incubation temperature. For some species, eggs with the same genotype developing at higher temperatures develop into a different sex type than eggs with that genotype developing at lower temperatures.In birds and some moths, males develop if embryos have two Z chromosomes and females develop if they have a Z and W chromosome.In ants and bees, diploid individuals are typically female while most males arise from unfertilized haploid eggs.In humans, XXY individuals are Klinefelter males.
