QQuestion
“Some phenotypes may have multiple genotypes and some other phenotypes may have a single genotype” — Justify the statement from the results derived from the dihybrid experiment in the case of the pea plant.
✓Answer
In the pea plant dihybrid experiment, the phenotype “round” can have multiple genotypes such as RR (homozygous dominant) or Rr (heterozygous), meaning different genotypes express the same phenotype. On the other hand, the phenotype “wrinkled” is expressed by a single genotype rr (homozygous recessive). Hence, some phenotypes correspond to multiple genotypes, while others correspond to a single genotype.
