3. In cats, the gene for calico (multicolored) cats is codominant. Females that receive a B or R gene have black and orange splotches on white coats. Males can only be black or orange, but never calico. Here's what a calico female's genotype would look like XB XR. Show the cross of a female black cat, with a male orange cat a) What percentage of the kittens will be calico and female? b) What color will all the male cats be?

1. In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the
allele for white is W. The heterozygous phenotype is known as erminette (black and white spotted) i#2
erminette chickens are crossed, what is the probability that:
They would have a black chick?
They would have a white chick?
2. Human blood types are determined by genes that follow the CODMINANCE pattern of inheritance. There are
2 dominant alleles (IA and 18) and one recessive allele (i).
