The father's genotype is heterozygous

the father would have one dominant allele (capital letter) and one recessive allele (lowercase letter)

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

we would need to see the picture to answer it
