Males have testes- also called testicles, while the females have a pair of ovaries. Also read: Sexual Reproduction Human beings have 23 pairs of chromosomes in the nucleus of the cell. Out of this two chromosomes are sex chromosomes X and Y. The female has two X chromosomes (XX) and male has one X and one Y chromosome (XY). The sperms and eggs have one set of sex chromosomes. Some sperms have X chromosome and some have Y chromosome. All eggs have X chromosome Thursday, February 2- PEP RALLY @ 1:00PM. Wear class colors!

Fission is an asexual reproduction that is common in most of the unicellular organisms. When the fission results in two daughter cells, it is binary fission (e.g. paramecium). When fission results in many daughter cells, it is called multiple fission (e.g. Plasmodium). Planes of fission may be different for different organisms Question 7 What is the average duration of human pregnancy? Reproduction in human beings The male gamete or sex cell is called sperm(it has long tail,motile and can move independently). The female gamete or sex cell is called ovum or egg(It contains water,stored food and nucleus). Fusion of egg and sperm give rise to a single cell called ZYGOTE.
