You\'ve discovered a new plant species in which

green fruit color (g) is recessive to yellow fruit color (G), and

long fruit shape (l) is recessive to round fruit shape (L).

The genes for fruit color and shape are located on the same chromosome and are 12 m.u. apart.

Determine the proportions of progeny of each phenotype produced for this cross.

Solution

When two genes are separated by 12 mu on same chromosomes, the percentage of recombinants produced in the cross would be about 10%. The distance between the genes is directly proportional to the percentage of recombinants produced.

Yellow round: 50%

Yellow long: 25%

Green round: 10%

Green long: 5%
