Question

ou've discovered a new plant species in which yellow fruit color (Y) is dominant to green fruit color (y), and round fruit shape (R) is dominant to long fruit shape (r). 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.

Incorrect; Try Again;

You filled in 4 of 4 blanks incorrectly. If two genes are 12 map units apart, recombination takes place 12% of the time, and it does not take place 88% of the time. With this in mind, gametes produced by the Yr/yR individual would not be produced in equal proportions.
