Who is responsible for the sex of the new born child. Male or Female? Explain.

Explanation

Male is responsible for the sex of new born child. Sex-determination in Humans is XX-XY type. Human female is homomorphic and homogametic i.e., have XX-chromosome and produce only one type of ovum with X-chromosome. Human male is heteromorphic and heterogametic i.e., have XY-chromosome and produce two types of sperms, 50% with X chromosome (gynosperms) and 50% with Y-chromosome (androsperm). The sex of the offspring depends upon the type of sperm, which fuses with the egg.
