In Tomato Plants, a Gene Controlling Fruit Shape Has 2

Multiple Choice

In tomato plants, a gene controlling fruit shape has 2 alleles: O (round) and o (oval) . A gene controlling inflorescence (position of the flowers) has two alleles: S (simple) and s (compound) . The map distance between the two genes is 22 cM. A pure-breeding plant with oval fruit and compound inflorescence is crossed with a pure-breeding plant with round fruit and simple inflorescence. The F₁ have round fruit and simple inflorescence. The F₁ are then crossed to plants with oval fruit and compound inflorescence and 100 offspring are produced. How many of the offspring would you expect to have oval fruit and simple inflorescence?

A) 22
B) 11
C) 39
D) 25
E) 50
