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. Meiosis: has something to do with the sperm and then genetic material from the male and female getting together. Step 2: crossing over (new/unique combos) a piece of one dna breaks off and switches with another one. A new unique combination that didn"t exist before.
