Explanation:
Detailed explanation-1: -Wrinkled (rr) seeds lack one isoform of starch-branching enzyme (SBEI), present in round (RR or Rr) seeds. A major polymorphism in the SBEI gene between near-isogenic RR and rr lines shows 100% cosegregation with the r locus, establishing that the SBEI gene is at the r locus.
Detailed explanation-2: -The shape of the pea seeds is controlled by two alleles. S is dominant alleles and stands for smooth and s is recessive allele and stands for wrinkled. The wrinkled phenotype is shown when the genotype contains both the recessive alleles. The genotype of the wrinkled seeds of pea is ss.
