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. So we have uppercase G, uppercase G, lower case and lowercase N. So uppercase G, uppercase G, lower case and lowercase N. And before they actually mates, they have to produce our gametes, the sex cells. And in this case, because we have female, these are going to be X cells. Now, because we're assuming these genes are linked, that means they're located on the same exact chromosome.
