A Drosophila geneticist made a cross between females homozygous for three X-linked recessive mutations (y, yellow body; ec, echinus eye shape; w, white eye color) and wild-type males. She then mated the F1 females to triple mutant males and obtained the results shown. What is the distance between genes ec and w?

A mating between a true breeding red, long-stamen plant with a true breeding white, short-stamen plant yields an red, long F1. This F1 is self-fertilized to produce an F2 generation that has 300 red long-stamen plants and 100 white short-stamen plants. What can you conclude? 1. The genes are tightly linked 2. The genes are not tightly linked 3. There were no observable crossover events between the genes
