Sagot :
There are two types of reproduction: Asexual and Sexual. Asexual reproduction mostly occurs with bacteria, or other one celled organisms. Sexual reproduction happens with multi-celled organisms, like humans, or whales. With asexual reproduction, the bacteria (for example) undergoes the process of fission: when the DNA splits it's two strands apart (into RNA) and repairs them into two identical strands of DNA. then, the strands move to opposite sides of the cell, and the cytoplasm (gel like interior of the cell) pulls apart, and pinches off. duplicating the cell. With sexual reproduction, the male haploid cell (sperm cell(half the usual amount of chromosomes)) binds with the female haploid cell (egg cell) and creates a zygote (fertilized egg). From there, the chromosomes uncoil into DNA, and the cell starts it's life processes. [i think,]
