Question

In the ZW–ZZ type of sex determination, the male produces:

विकल्प

• A+Z and A+W sperms

• A+Z and A+O sperms

• Only A+Z sperms

• A+X and A+O sperms

Answer 1

In the ZW–ZZ type, the male is ZZ (homogametic) and therefore produces only one kind of sperm, A+Z. Since the female produces A+Z and A+W ova, the type of ovum fertilized determines the sex of the offspring.
