1. Environmental based sex determination.

2.Genetic based sex determination.

Environmental based sex determination:

1. In some reptiles, the temperature at which the fertilized egg is incubation before hatching plays a very important role in determination of sex of new born.

2. In turtle, high incubation temperature leads to development of female offspring.

On the other hand , in case of lizard, high incubation results in male offspring.

3. In some animals like snails, individual can change sex indicating that sex is not determineddetermine genetically.

Genetic based sex determination :

For example in human beings , the sex of individual is largely genetically determined.
