Question

Which allele will be expressed when both

a dominant and recessive allele are
present in an organism?
A. dominant only
B. recessive only
C. the two alleles will mix

Answer 1

A. Dominant only

Step-by-step explanation:

A dominant allele needs to be present in only one gene (so in the gene Qq, only Q would be present)

However, in order for a recessive allele to be present, it needs to have two genes (so in the gene qq, the recessive gene would be present)
