Assume that in humans, red hair color (allele

) is epistatic to shades of black/brown/blonde (loci B). This would mean that as long as a person is homozygous recessive for "

", they will have red hair regardless of their "B/b" allele. You are creating a pedigree for hair color in a large, multigenerational family. What information would be revealed by noting the shade of red hair rather than just whether or not a person has red hair? Whether the trait was epistatic. If there was variable expressivity in the amount of red pigment. If there was reduced penetrance with the "

" allele. If red hair was
