Question

A plant that has round and yellow seeds (RrYy) is crossed with a plant that has round and yellow seeds (RrYy). What is the ratio of the offspring that will have round and yellow seeds?

Answer 1

To determine the ratio of offspring that will have round and yellow seeds, we need to use the principles of Mendelian genetics and Punnett squares.

First, we need to determine the possible gametes that can be produced by each parent. Since both parents are heterozygous for both traits (RrYy), they can produce four different gametes each: RY, Ry, rY, and ry.

Next, we can use a Punnett square to combine the gametes from each parent and determine the genotypes and phenotypes of their offspring.

Answer: the ratio of offspring that will have round and yellow seeds is 1:2
