The student inherited a recessive phenotype because both parents are likely heterozygous for that trait, meaning they carry one dominant allele and one recessive allele (e.g., Aa). Although they display the dominant phenotype, they can still pass on the recessive allele to their offspring. If the student received the recessive allele from both parents (aa), they will express the recessive phenotype despite the parents being phenotypically dominant. This scenario illustrates the principles of Mendelian genetics and inheritance patterns.
