Mechanism of Sex Determination in Human Beings:
In human beings, the sex of the individual is genetically determined.
- Sex determination is the process by which sex of a new born individual can be determined.
- Human beings have 1 unpaired sex chromosome. Sex chromosome of male is XY and of female is XX.
- Sex of a child depends on what happens at fertilisation.
Thus, father is responsible for the determination of the sex of a child.
