It is known as proliferative phase by the multitude of mitoses that occur. The main objective is to form many sperm precursor cells, i.e., many spermatocytes. Meiotic phase Also known as spermatocytogenesis, this is the stage at which a new type of cell division, meiosis, begins, which ...
How Big Is My Baby This Week? Zygote vs. Embryo: What's the Difference? A chromosomally normal zygote has 23 pairs of chromosomes. At the time of fertilization, it has only one cell (made when the sperm cell combines with the egg cell). "The genetic information in these cells then cau...
During fertilization, a sperm cell will fuse with an egg cell that, in a successful pregnancy, will then implant in the uterus. The fertilized egg will then mature into what's called a blastocyst, then an embryo and, finally, a fetus. A placenta forms to support this process. The ...

coli cell. When a female creates an egg or a male creates a sperm, the two strands of DNA must combine into a single strand. The sperm and egg from the mother and father each contribute one copy of each chromosome. They meet to give the new child two copies of each gene. To form ...
