Step 4
The characteristic “spotted” is coded for by the recessive allele a. Yan ('1', see above) has a plain coat because he is homozygous for the dominant allele. Sins ('2') first question is: “What is the chance of having spotted offspring if I choose to reproduce with Yan?” Work out your cross on paper and give an answer to that question expressed in a percentage.
Krad ('3') is heterozygous for this characteristic, like Sin. Work this cross out on paper too and see what chances Sin has of getting spotted children with Krad.
