A new recessive mutation in chickens that causes feather loss from the wings is being investigated. Describe the expected progeny phenotypes from a cross between a hen with feather lesswings and a true-breeding wild type rooster if:
a. The gene coding for feather loss is on the Zchromosome
b. The gene coding for feather loss is on the Wchromosome.
c. The gene coding for feather loss is on an autosome.
Remember that, in chickens, the homogametic and heterogametic sexesare the reverse of those in mammals: females are WZ and males areZZ.
