Question

Discuss the genetic basis of wrinkled phenotype of pea seed

Answer 1

Hey..
Here is your answer.

Basically, Seed shape is determined by a single gene
For example:-Lets say allele for round peas is denoted as (R) ,(Dominant trait)
and allele for wrinkled peas is (r) (recessive trait).
Alleles are responsible for the gene controlling.And hence if the seed shape are homozygous in a plant, it will show the character or phenotype of same alleles, i.e., RR-round seed, rr-wrinkled seed.

On the other hand, if the alleles of gene are heterozygous, they will express the phenotype of dominant allele. Rr - Round seed (r- wrinkled is recessive).

This is the genetic basis of wrinkled phenotype of pea seed.

Hope it helps.
Have a good day.

Answer 2

Seed shape is determined by a single gene, with the allele (R) for round peas dominan tover the allele (r) for wrinkled peas (recessive trait).

It the alleles for the gene controlling the seed shape are homozygous in a plant, it will show the character or phenotype of same alleles, i.e., RR-round seed, rr-wrinkled seed.

On the other hand, if the alleles of gene are heterozygous, they will express the phenotype of dominant allele. Rr - Round seed (r- wrinkled is recessive)

This is the genetic basis of wrinkled phenotype of pea seed.
