Humans normally have 46 chromosomes, which come in 23 pairs, as well as some mitochondrial DNA. From the mitochondrial DNA, and 22 of the 23 other chromosome pairs, there is nothing to tell you whether the DNA came from a male or a female. The genetic difference between males and females resides in that last chromosome pair, the sex chromosomes. At the sex chromosomes, women have two X chromosomes, while men have one X chromosome and one Y chromosome. So, if you have a discrete source of your DNA sample, like a hair, you could do a couple of things. You could test it for the presence of Y-chromosome genetic material.
Summary: 1  The most obvious difference: a sperm cell is a reproductive cell of males while egg cells are of females. 2  Both egg cells and sperm cells depend on each other for the reproduction of a human life. 3  Both egg cells and sperm cells undergo meiosis.n the process of sperm cell formation, a motile spermatozoa is produced. While in egg cell formation, an ovum in spherical in shape and immobile. It is produced and is bigger in size than the sperm cell. There is also a difference on how these cells are produced and it involves hormones.
