In chickens, males have two Z sex chromosomes (ZZ) and females have one Z and one W sex chromosome (ZW). The mechanism for inheritance of the sex chromosomes is exactly the same as for X and Y sex chromosomes in other species. In chickens the character of ‘barred’ or striped feathers is Zchromosome linked. The barred feather allele ZB is dominant to the nonbarred feather allele Zb. Write down the genotype that would result in a nonbarred male and a barred female and explain why these are the only genotypes that could result in these phenotypes.
