If a recessive trait is visible, what conclusion about its gene forms is correct?

Answer and explanation

Correct answer: Both gene forms will be recessive

The governing concept is dominance in a Mendelian genotype. A recessive phenotype appears only when the individual has two recessive alleles, commonly written aa. If one dominant allele, A, were present in Aa, it would usually mask the recessive allele and produce the dominant phenotype. Therefore option A is correct. Options B and C would normally produce a dominant appearance, while D is biologically impossible because a trait requires genetic information.
