Dominant
B
Recessive
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -So the answer choice that best describes what recessive means is “A recessive allele will only be expressed in the phenotype if two copies of it are present.”

Detailed explanation-2: -A recessive trait is a trait that is expressed when an organism has two recessive alleles, or forms of a gene.

Detailed explanation-3: -Dominant is always a capital letter and Recessive is always a lower-‐case letter. Here is where I write down the letters that represent my couple. Because they are heterozygous, I use one capital letter and one lower letter since they have both traits in their genes.
