Step 6
Secunda is not sure if she has a preference for a certain eye colour. Though at this point she thinks it will not be a part of the choice she has to make, she still asks you to make some calculations.
A Zokky's eye colour is caused by protein g. The gene responsible for this protein knows two X-chromosome bound (X-linked) alleles: XG causes the eyes to be green, Xg gives red eyes.
Secunda is homozygous for this trait. Her question is: “What is the chance that I get a male child with green eyes?” Calculate this chance for both potential partners.
