In cucumbers normal leaves (N) are dominant to curled leaves (n) and elongated fruit (L) is dominant to spherical fruit and these genes are linked on the same chromosome. If a pure-breeding normal-leaved, elongated fruit cucumber is crossed with a curled-leaved, spherical fruit cucumber, what will be the phenotype of the F1? the phenotypic ratio of the F2?

Cystic fibrosis (CF) occurs with a frequency of about 1/2500 Caucasian newborns and is inherited as an autosomal recessive. A woman had an older sister die from complications of this disease. CF is not present among relatives of her husband. Both the woman and her husband have normal phenotypes. What is the chance this couple will have a CF child?

Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene.

In horses coat color is dependent upon genes as follows: A_B_ results in bay, aaB_ in black, A_bb in chestnut, aabb in liver. In addition, palimino is derived by Dd with chestnut. A palimono stallion (DdAAbb) is crossed with a palimino mare (DdAAbb). What percent of the offspring will be palimino?
