Genotypically $Aa$,phenotypically $A$

(C) When a cross is performed between a homozygous dominant parent $(AA)$ and a homozygous recessive parent $(aa)$,the gametes produced by $AA$ are $A$ and the gametes produced by $aa$ are $a$.Upon fertilization,the fusion of these gametes results in the ${F_1}$ generation with the genotype $Aa$.Since $A$ is the dominant allele,the phenotype of the ${F_1}$ progeny will express the dominant trait $(A)$.
