Why can a hidden recessive trait reappear in the second generation?

Answer and explanation

Correct answer: Because recessive information can come from both parents

A recessive allele is expressed in the phenotype only when a person receives two copies of it, one from each parent. It may remain hidden in a heterozygous first-generation individual because a dominant allele masks it. During the next cross, two recessive alleles can unite in an offspring, allowing the trait to reappear. Therefore option A is correct.
