Question

A dihybrid cross: 2 genes-2 alleles for each gene. What happens if we cross a true-breeding red-eye, spineless male chupacabra with a true- breeding green-eye, spiny female one? How do we determine the gametes of these male and female chupacabras? First, we must determine the genotypes of the parents. Because they are true-breeding, we know that they are homozygous. The phenotype of the male is red-eyed, spineless. His genotype is RR (red-eye) ss (spineless) or RRss. The phenotype of the female is green-eyed, spinny. Her genotype is $rr$ (green eye) SS (spiny) or $rrSS$
