You have two flies that have the following traits. The female fly is dominant homozygous for red eyes and she has a rate immune deficiency for which she is recessive homozygous, having one allele on each X-chromosome. The male fly has recessive homowzygous white eyes and does not have a recessive allele for the immune deficiency on his X-chromosome. The F1-generation consists of 387 offspring and the F2 generation consists of 405 flies.
a) What are the chances for each fly in the F1 and F2 generation to have the immune deficiency?
b) What are the ecpected numbers of flies with red and white eyes in both generations?
c) What is the chance for the male offspring to inherit the recessive allele for immune deficiency?
