Answer:
<h2>E. normal roosters & hens and bald roosters & hens.</h2>
Explanation:
The sex chromosomes of the chickens are represented by ZZ for male chicken that is rooster and ZW for the female chicken that is hen.
In the given question, the genotype of the bald rooster is zz and the genotype of the normal hen is ZW.
So the F1 progeny are, Zz that is normal male and the zW that is bald female.
So F1 × F1
Zz × zW
Thus, F2 progeny are Zz ( normal rooster), zz ( bald rooster), ZW ( normal hen), zW ( bald hen).
