Hey guys, If anyone could help me out I would be grateful! I have no idea what the genotypes are for these. I thought maybe ZbZ for the male, and ZBW For the female... But that seems too easy.
Any help appreciated. Thank you!
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 Z-chromosome linked. The barred feather allele ZB is dominant to the non-barred feather allele Zb. Write down the genotype that would result in a non-barred male and a barred female and explain why these are the only genotypes that could result in these phenotypes.
