What is a trait called when it remains hidden in the first generation?
Answer and explanation
Correct answer: Recessive trait
The governing concept is dominance and recessiveness in Mendelian inheritance. When two contrasting alleles are present, a dominant allele masks the expression of a recessive allele in the first generation. Thus, a trait that remains hidden is called a recessive trait. It can reappear in a later generation when the offspring receives two recessive alleles. Therefore, option A is correct; a dominant trait is expressed, while acquired and fossil traits are different concepts.
