A dog's coat color and pattern is determined by many genes, including the two autosomal genes S and A. S (solid) is dominant to s (spotted), and A (black) is dominant to a (tan). A female with a solid tan coat is mated with male having a solid black coat. The puppies are 2 solid tan, 2 solid black, 1 spotted tan, 1 spotted black. What are the most likely genotypes of the parents? (assume the genes are on different chromosomes) female parent is SS aa, the male is SS AA female parent is SS Aa, the male is SS aa female parent is Ss aa, the male is Ss Aa female parent is SS aa, the male is Ss Aa
