The blood type A allele (IA) and blood type B allele (IB) are both completely dominant over the blood type O allele (i). The Blood type A allele and blood type B allele are codominant. A woman is blood type B and has 3 children with a partner of unknown blood type. One child is blood type A and 2 children are blood type O.  What is the probability that child number 4 will be blood type B?

Consider the following three genes in Mendel’s pea plants: Tall height (T) is dominant over dwarf height (t) Green pods (G) is dominant over yellow pods (g) Round seeds (R) is dominant over wrinkled seeds (r)   In a cross between the parents, TtGgrr x TtggRr, what proportion of offspring will be tall and produce yellow pods and round seeds. (HINT: consider each gene separately and then apply the product rule)
