In Drosophila, males(XY) produces two different types of gamete while females (XX) produce same type of gametes.

Male grasshoppers have only one sex chromosome (XO). Therefore, some of the sperms bear the X-chromosome whereas some do not.

The karyotype of sperm is the same in fowls, i.e. ZZ.

The total number of chromosomes is different in male and female honey bees.
