Step 9
The blue irises some Zokkies have are regulated for by allele B. Allele B alone is not enough: This trait is polygenous. When allele XG, the allele for light eyes, can be found in the genotype the eye becomes blue. If XG is not present the iris still becomes grey.
Yan is heterozygous for the protein B allele. Sin has tested positive for the B allele, she is heterozygous too.
Use the form in source 2 again to perform a dihybrid cross for both potential partners.
Sins question is: “With which of the two males is the chance that one of my female offspring has green eyes the highest?”
Remember to add the genotype for the eye shade in your cross!
