1. Assume you are studying fruit fly wing development. The wingless gene determines the shape of wings. The phenotype associated with the dominant allele, W, is normal wing development. The phenotype associated with the recessive allele, w, is a wing with notches. You cross a true breeding fly having normal wings with a true breeding fly with notched wings.
a. What is the genotype and phenotype of the offspring of this cross?
b. If you crossed male and female offspring from the first cross, what are the resultant genotypic and phenotypic ratios?
c. Which genetic law was demonstrated by these crosses?
