dominant allele
B
codominance
C
recessive allele
D
Punnett Square
Explanation: 

Detailed explanation-1: -Recessive alleles are denoted by a lowercase letter (a versus A). 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.

Detailed explanation-2: -A recessive allele is hidden whenever the dominant allele is present.

Detailed explanation-3: -The recessive allele is hidden and not expressed when a dominant allele is present. The recessive allele is only expressed when an organism has two recessive alleles.

Detailed explanation-4: -A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).

Detailed explanation-5: -Uppercase letters represent dominant alleles and lowercase letters indicate recessive alleles.
