Q1. Body colour gray of Drosophila is dominant and recessive allele produces black. A testcross of a wild type female produces 52 black and 58 types F1. If the females are crossed to their F1 black brothers, what genotypic and phenotypic ratios will be expected in the F2?

Q2. Black coat of animal is dominant; white is the alternative recessive. While true-breeding black is crossed to true-breeding white, what is the possibility that a black F2 is heterozygous?
