1 Germ cells have only half the number of chromosomes as a diploid cell Â­ one of each pair-and are termed haploid (n) . 2  In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y. 3  The number of chromosomes is reduced from 46 to 23 during the process of meiosis.
Haploid. Haploid is one-half of the total number of chromosomes in a gamete. A full set of chromosomes is called Diploid. In humans, the egg and sperm each have a set of 23 chromosomes.Therefore each is haploid.When they come together to form a fertilized egg, the total set of chromosomes is then 46 and is diploid.aploid.
