Question

Which best describes a recessive allele?

a)always inherited from a parent when a dominant allele is inherited from the other parent
b)never inherited from a parent when a dominant allele is inherited from the other parent
c)only determines phenotype when a dominant allele for the same trait is present
d)does not determine phenotype when a dominant allele for the same trait is present

Answer 1

Answer: The answer is c

Explanation: Recessive Allele Definition. A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. In a dominant/recessive relationship between two alleles, the recessive allele’s effects are masked by the more dramatic effects of the dominant allele.

Answer 2

C.only determines phenotype when a dominant allele for the same trait is present.
