Jimena Berger · Answer 1

Genotype of each parent would be "Gg"

Explanation:

Let "G" represents gary seed color peas while "g" represents white seed color peas.

also "G" is dominant over "g"

The ratio of gray vs white offspring is

302:98

If this simplifies, it becomes

3:1

Thus, there are 3 times gray peas as compared to the white one.

Now as per Mendel's rule,

the genotype of 3 three gray peas would be GG, Gg and Gg

So the genotype of parent would be

Gg x Gg
