Now, normal wings which are functional are given by uppercase N and vestigial wings, which are nonfunctional, are given by lowercase N. So in this example, in this experiment, we're basically mating a female individual that is homozygous dominant for the color trade and homozygous recessive for the wing trade with a male individual. So we're mating this with a male individual that is homozygous recessive for the color and homozygous dominant for the wing type. Now, in a what is the genotype of the f one generation offspring that is produced when we make these two individuals? To actually determine what the genotype is, we first have to answer the question what are the gametes produced? What are the gametes that are produced by these two types of individuals? So let's begin with our female individual.
