Which statements describe codominance? Choose three answers.Traits are usually dominant.Traits are neither dominant nor recessive.Offspring exhibit an intermediate form of alleles from the parents.Both alleles, one from each parent, are expressed in offspring.Codominance involves the interaction of two alleles.
Answer
A
Traits are usually dominant.
B
Traits are neither dominant nor recessive.
C
Offspring exhibit an intermediate form of alleles from the parents.
D
Both alleles, one from each parent, are expressed in offspring.
E
Codominance involves the interaction of two alleles.
Explanation
In codominance, neither allele masks the other, so the traits are neither dominant nor recessive. Both alleles—one inherited from each parent—are expressed in the offspring, which means codominance involves the interaction of two alleles. An intermediate form describes incomplete dominance, not codominance.
