Q1. In Drosophila, yellow eyes, Y, are dominant to grey eyes, y. In an experiment, Dr. D breeds two individuals, one with yellow eyes and the other with grey. He finds the offspring to be 131 yellow and 58 greys.
1. What are genotypes of the adult that were crossed?
2. What is the expected proportion of individuals in each group and do these numbers significantly differ?
3. Are there other probable genotypes for the adults? Is there statistical support for them?
Q2. 10 percent of a population died from sunburn, of the 10 percent who died 10 individuals were albino and the rest were split evenly between heterozygous (Gg) and dominant individuals (GG). So my question is how various individuals are Gg and GG?
