Please help me!! what is the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy?

3/16

Explanation:

This question involves two genes coding for pea shape and pea color. The alleles for yellow color (Y) and round seeds (R) are dominant over the alleles for green color (y) and wrinkled seeds (r).

In this cross between two heterozygotes: RrYy × RrYy, the following allele combinations are produced in the gamete of each parent: RY, Ry, rY and ry. Using these gametes in a punnet square (see attached image), the following offsprings are produced:

9/16 of Round, yellow offsprings (R_Y_)

3/16 of Round, green offsprings (R_yy)

3/16 of Wrinkled, yellow offsprings (rrY_)

1/16 of wrinkled, yellow offsprings (rryy)

Hence, the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy is 3/16.

answer; i believe the correct answer is (replication is not conservative);

there is no
