Question

A recessive allele does not affect the phenotype of a heterozygous person.

A. True

B. False

Answer 1

Answer: A. true

Explanation: The phenotype is the physical characteristics of a person. So, if a person has brown eyes, which may be a characteristic that is dominant, then they would have a genotype of BB or Bb. The reason why Bb, heterozygous, is not a different color is because the recessive b does not affect the dominant B allele.
