Solution
ZZ/ZW type of sex determination is seen in peacock.

The ZZ/ZW type of sex determination is seen in birds, many fishes, and reptiles. In this system, the female is heterogametic (ZW), meaning she produces two types of eggs,one with the Z chromosome and one with the W chromosome. The male is homogametic (ZZ), producing only one type of sperm with the Z chromosome.
