In cats with tortoiseshell coat color, the fur is white with
patchy black and orange spots. In cats, the tortoiseshell gene is
on the X chromosome, and the tortoiseshell phenotype requires the
presence of 2 different alleles at this locus: one for orange fur
(o) and one for black fur (b). Which phenomenon best explains why
female cats can inherit tortoiseshell coat color?
(A. In females, the alleles for coat color are pleiotropic,
resulting in patches of orange and black coat color.
B In females, these coat color alleles show incomplete dominance,
but in males, the coat color alleles do not.
C Females typically express both the orange and the black allele in
each cell (alleles are co-dominant), making orange and black coat
color possible.
D Females are mosaic with respect to their X chromosomes, because
in each cell, one of the X chromosomes is randomly
inactivated.)
If a black female cat mates with an orange male cat, what proportion of their female offspring are expected to be tortoiseshell cats?
