How is sex determined in organisms?

Solution

Different species use very different strategies for determination of sex of new-born individual. In some animals the temperature at which the fertilized eggs are kept determines the sex of the newborn (e.g., crocodiles). In other animals, such as snails, individuals can change sex, indicating that sex is not genetically determined. However, in human beings, the sex of the individual is largely genetically determined.
