The purpose and stages of development. ... They occur via four essential stages in early animal development: Fertilization: the process of a single sperm cell combining with single egg cell to form a zygote. Cleavage: rapid, multiple rounds of mitotic cell division where the overall size of the embryo does not increase.
In humans, the haploid cells have 23 chromosomes, versus the 46 in the diploid cells. There is a difference between haploid and monoploid cells. ... In diploid organisms, diploid cells contain the complete set of necessary chromosomes, while haploid have only half the number of chromosomes found in the nucleus.
