How can two organisms have the same phenotype but different genotypes?
balu736 [363]

Two organisms have the same phenotype but different genotypes when One organism is purebred dominant, and the other organism is heterozygous. So, the correct option is B.

<h3>What do you mean by Genotype?</h3>

Genotype may be defined as the ultimate combination of those alleles which are selected for specific studies.

When an allele is dominant over others, its purebred dominant and heterozygous (hybrid) may have different genotypes but the same phenotype.

Therefore, the correct option for this question is B.
