There isnt enough info to do this problem… it is a simple Punnet square, but you didnt tell us if the dominant allele is homozygous or heterozygous. the chances will be different if it is hetero vs. homozygous.
ALso, just to be a knit picker… generally dominant allele would be for “not cancer” and the recessive trait would be ” cancer developing”. Recessive= bad things generally speaking in Genetics.
So, let me know if 1 parent is HETERO or HOMOZYGOUS Dominant for cancer, and then Ill figure it out.
