  4. DAll of the above

Correct answer

D. All of the above

Step-by-step solution

In this case the total number of chromosomes is the same in both males and females. But two different types of gametes in terms of the sexchromosomes, are produced by females, i.e., female heterogamety. In order to have a distinction with the mechanism of sex determination described earlier, the two different sex chromosomes of a female bird have been designated to be the Z and W chromosomes. In these organisms the females have one Z and one W chromosome, whereas males have a pair of Z-chromosomes besides the autos
