What term describes an allele that is masked or covered/dominated up by another allele? A. Recessive Allele
B. Dominant Allele
C. Homzygous
D. Heterozygous

A.

Explanation:

A recessive allele is an allele that gets covered up by a dominant allele.

Example -

Lets say that two people were breeding. Brown hair would be the dominant trait, with blonde as a recessive. If the male has the allele Bb, and the female has bb, then you would put these into a table. Your outcome would come as

      B       b

b    Bb     bb

b    Bb     bb

So there would be a 50/50 chance of the offspring having brunette or blonde hair.

Hope this helps!
