In cats, blood type A results from an allele (A) that is dominant over an allele (B) that produces blood type B. There is no O blood type, following two cross are
a. blood type A X blood type B = 4 kittens with blood type A, 4 with blood type B
b. blood type A X blood type A = 6 kittens with blood type A, 3 kittens with blood type B. What are genotype of parent

In cucumbers, dull fruit (D) is dominant over glossy fruit (d), orange fruit (R) is dominant over cream fruit (r), and bitter cotyledons (B) are dominant over non-bitter cotyledons (b). The three characters are encoded by genes located on different pairs of chromosomes. A plant homozygous for dull, orange fruit and bitter cotyledons is crossed with a plant that has glossy, cream fruit and nonbitter cotyledons. The F1 are intercrossed to produce the F2. What will be expected proportions progeny with Dull, Orange and non-bitter?
