Discuss the genetic basis of the wrinkled phenotype of pea seed.
Seed shape is determined by a single gene, with the allele (R) for round peas dominant over the allele (r) wrinkled peas (recessive trait).
If 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 phenoty[e of the dominant allele.
Rr Round seed (r wrinkled is recessive)
This is the genetic basis of the wrinkled phenotype of pea seed.
