Question

Which of the following effects does the recessive allele have in an organism which also displays a dominant allele?

A.the recessive allele will turn into a dominant allele
B.the gene will have a disorder
C.the dominant allele will become recessive
D.it has no effect

Answer 1

Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait. One example of a recessive inherited trait is a smooth chin, as opposed to a dominant cleft chin.

Answer 2

The answer would be D. It has no effect.

The dominant allele is the one that gets expressed. So a heterozygous individual(for a particular gene) has the same phenotype(characteristics) as a homozygous dominant individual.
