Answer:
If an individual has a dominant phenotype it is not known what the exact genotype is. For example with the phenotype of brown eye color , the genotype could be heterozygous.
Step-by-step explanation:
Dominant is a trait that shows dominance over a recessive trait. The dominant trait might have a heterozygous or homozygous genotype.
For example, if the brown eye is a dominant phenotype, it might be that a person might have a heterozygous genotype for this trait. One of the alleles might be the dominant one while the other allele might be recessive. In such a case, the effect of the recessive trait is masked by the dominant trait. Hence, the organism shows the dominant phenotype but has a heterozygous genotype.
