If the dominant form of a trait is present, what can happen to the recessive form?
Answer and explanation
Correct answer: It may not appear but can remain as genetic information
Dominance describes expression, not destruction of an allele. When a dominant allele is paired with a recessive allele, the dominant phenotype is usually visible, while the recessive allele remains present in the genotype but is masked. Therefore, option A is correct. The recessive form is not automatically destroyed or converted into a dominant form, and it cannot destroy a chromosome.
