The sperm cells have only 23 chromosomes, or half of the usual number. Some of the genes that regulate spermatogenesis have been conserved in evolution from flies to humans. Abstract Funding Institution Publications Comments. Sperm differentiation is therefore directed by the products from both parental chromosomes, even though each nucleus is haploid. The egg is among the largest cells in an organism, while the sperm spermatozoon , plural spermatozoa is often the smallest. The DAZ gene , for example, which encodes an RNA -binding protein and is located on the Y chromosome , is deleted in many infertile men, many of whom cannot make sperm.

This explains why you might have your dad's eye color and height, but your mom's hair color and body type. National Center for Biotechnology Information , U. What's your main goal? The main and most obvious difference is that egg cells are produced in the female reproductive system, while sperm cells develop in the testes, which are part of the male reproductive system. If you ever found yourself in a chicken coop, it is safe to say you would most likely stumble upon a few chickens as well as their eggs.

The sperm subsequently pass into the epididymis, a coiled tube overlying the testis, where they undergo further maturation and are stored. Anyone can earn credit-by-exam regardless of age or education level. The cytoplasm is the interior of the cell that surrounds the nucleus and is around 80 percent water; it includes the organelles and a jelly-like fluid called the cytosol.
Flagella propels the sperm cell to reach the egg. What organelle directly provide energy for sperm cells? It is different from other cells because it only has half the chromosomes, otherwise known as a haploid cell. In this way, it can be supplied with all the products of a complete diploid genome. The fusion of the sperm cell with the oocyte cell generates a new individual containing half of their genetic material from the maternal parent and half from the paternal parent.
