The X-linked barred locus in chickens controls the pattern of the feathers, with the alleles $B$ for barred pattern and $b$ for no bars. If a barred female $\left(X^{B} Y\right)$ is mated to a nonbarred male $\left(X^{b} X^{b}\right)$, what will be the appearance of the male and female progeny? (Recall that in birds males are $\mathrm{XX}$ and females are XY.) Do you see any commercial usefulness for this result? (Hint: It is notoriously difficult to determine the sex of newly hatched chicks.)
