How can a recessive trait remain in a population even when it often does not appear?

Answer and explanation

Correct answer: It can pass through generations in hidden form with a dominant form

The governing concept is allele masking in a heterozygous genotype. When a recessive allele is paired with a dominant allele, the dominant phenotype may appear, so the recessive trait is not visible. However, the recessive allele remains in the DNA and can enter gametes. If two carriers reproduce, their offspring may inherit two recessive copies and express the trait. Thus option A is correct.
