Show Answer
Answer:
Correct Answer: A
Solution:
In birds, including domesticated fowls, the sex of the progeny is determined by the type of egg rather than the sperm. Female birds are heterogametic (ZW), and males are homogametic (ZZ). Therefore, the sex of the offspring is determined by whether the egg carries a Z or a W chromosome.
