Answer: YY, Yy, and yy are genotypes. Green and yellow are phenotypes.
Explanation: Genotypes are the genes that cause phenotypes (YY, Yy, yy).
Phenotypes are the physical changes caused by a gene, like Blond hair.
Example: If I had recessive blond hair (lowercase genotype), then the genotype is maybe ww, as the dominant trait is white. The phenotype, or physical change is blonde hair.
