Answer:
A or/and D
Explanation:

both alleles in the heterozygous
genotype are exhibit in the phenotypes. Allele
is completely dominant over the other, and it is the phenotype is a blend of the two
homozygous phenotypes, there are more than two forms of the same gene, and
there maybe one more superior form and several different phenotypes
