In beans the pod texture and growth form genes are located on different chromosomes. There are two varieties of beans in a farmer’s field. One has tough pods (T) and a bush-type growth form (B). The second has tender pods (t) and also has a climbing-type (b) growth form. A farmer starts a breeding program with these two homozygous (= true breeding) varieties. The F1 plants are then self-crossed to produce an F2 generation.
a. What is the genotype and phenotype of the F1?

b. What proportion of the F2 are heterozygous for bush-type growth form?

c. What proportion of the F2 have tender pods?

d. What proportion of the F2 are heterozygous for growth form and have tender pods on the same plants?
