###### Problem Details

In chickens and other birds, the chromosomal basis of inheritance is the opposite of that in humans; i.e., in birds, ZZ homogametic individuals are males , and ZW heterogametic individuals are females .

In chickens, barred plumage is dominant to non-barred plumage; the gene is Z-linked.

Suppose that you were a poultry breeder and that you needed large numbers of  barred males and nonbarred females . Describe a breeding stock that you could assemble for this purpose, which would produce only barred males and nonbarred females.

Be certain that you show the genotypes of both the roosters and the hens in your breeding stock and also the genotypes of all the offspring that this stock will yield.
