Which statement shows correct understanding of a recessive trait?
Answer and explanation
Correct answer: It can hide in the presence of a dominant trait but is not lost
The governing concept is dominance in Mendelian inheritance. In a heterozygous individual, a dominant allele can determine the observable phenotype while the recessive allele remains present in the genotype. The recessive trait is usually expressed when suitable recessive alleles occur together, such as in a homozygous condition. Therefore A is correct. It does not appear in every condition, is not automatically lost, and is not defined as an acquired trait.
