Question

If a yellow pea plant with round seeds that has the genotype GgWw is crossed to itself, what proportion of the offspring will be green with round seeds?

Answer 1

Approximately 33.33% of the offspring will be green with round seeds.

Step-by-step explanation:

If a yellow pea plant with round seeds that has the genotype GgWw is crossed to itself, the Punnett square can be used to determine the proportion of offspring that will be green with round seeds.

1. Write out the genotypes of the parent plants: GgWw x GgWw.
2. Expand the genotypes to show all possible combinations: GGWW, GGWw, GgWW, GgWw, GGww, Ggww, ggWW, ggWw, gww.
3. Identify the genotypes that result in green color with round seeds: GgWw, Ggww, ggWw.
4. Count the number of genotypes that result in green color with round seeds (3 in this case).
5. Calculate the proportion by dividing the number of genotypes with green color and round seeds by the total number of genotypes (3/9 = 1/3).

Therefore, 1/3 or approximately 33.33% of the offspring will be green with round seeds.
