what is sex determination?
Asked by Chandranath Jha | 9th Mar, 2011, 10:54: PM
Sex determination is the establishment of male and female individuals or male and female organs of an individual.
It can either be due to environmental, genetic or chromosomal factors.
example- In some lizards, high temperature induces maleness while low temperature induces femaleness.
example- In bacteria, fertility factor present in a plasmid determines sex.
example- In mammals, females possess two homomorphic sex chromosomes XX whereas males contain two heteromorphic sex chromosomes XY.
We hope that clarifies your query.
