Document Summary
200 500 sperm from the male will travel up the vagina through the cervix into the uterus into the fallopian tube, fertilization occurs. Only the first one gets in and then the door closes so no more get in. Sperm releases its dna and ovum releases its dna and then they combine. Mitosis: start off with one cell and then it divides and makes 2 cells, then 4, etc. Then it travels its way back down the fallopian tube and attaches itself to the uterine lining and the mothers body nourishes it and it grows into the fetus. Step 3: splits into two, go to separate sides. Meiosis: has something to do with the sperm and then genetic material from the male and female getting together. Has to do with how we are each unique. Can get strange mutations, and diseases, down side of meiosis. In testes/ ovaries: germ cells -> gametes (sperm, ova)
