sergejj [24]

Answer:

Genotype of the parental plant that produced round, yellow seeds is RRgg

Explanation:

Let us say that allele for round shape (R) is dominant over allele for wrinkled shape(r)

and allele for green color (G) is dominant over allele for yellow color of seed.  

So a wrinkled green seed will have genotype either "rrGG" or "rrGg"

Like wise a round, yellow seeds will have genotype either "RRgg" or "Rrgg"

It is given that In the F1 generation, half of the plants produced round, yellow seeds and the other half produced round, green seeds.

So if a cross is carried between rrGg and RRgg, the following offspring will be produces

rG          rG         rg         rg

Rg RrGg RrGg Rrgg Rrgg

Rg RrGg RrGg Rrgg Rrgg

Rg RrGg RrGg Rrgg Rrgg

Rg RrGg RrGg Rrgg Rrgg

So genotype “RrGg” gives round and green seeds

And genotype “Rrgg” gives round and green seed

Thus, genotype of the parental plant that produced round, yellow seeds is RRgg
