Also describe as to who determines the sex of an unborn child ? Mention whether temperature has a role in sex determination.

Explanation

As a rule the heterogametic organism determines the sex of the unborn child. In case of humans, since males are heterogametic it is the father and not the mother who decides the sex of the child. In some animals like crocodiles, it is the temperature which decides the sex of the organism. Lower temperature favour hatching of female offsprings. Higher temperatures lead to hatching of male off springs.
