Question

gray seed color in peas is dominant to white. assume that mendel conducted a series of experiments where plants with gray seeds were crossed amoung themselves, and the following progeny were produced: 302 gray and 98 white. what is the most probable genotype for each parent

Answer 1

Genotype for both the parents will be Gg when it is give that Gray (G) seed color in peas is dominant to white(g)

Step-by-step explanation:

Given -

Gray (G) seed color in peas is dominant to white(g)

Gray seeds are crossed among themselves to produce
`302` gray and
`98`white seeds.

If we convert these number then it will be written as follows -

Gray : white

`302:98\\3:1`

Thus, most possible genotype of gray species is heterozygous dominant gray i.e Gg

Gg X Gg

GG, Gg, Gg,gg

GG, Gg will be gray and gg will be white

Thus, phenotypic ration is

Gray : white

`3:1`

Hence genotype of both the parents is Gg
