Sexual Reproduction
There are two types of " baby making" in organism. Those two types are Prokaryotic and Eukaryotic organisms. Prokaryotic Organisms The bacteria first goes through the cell cycle, so that they are asexual. During the process one prokaryotic cell produces another one. The offspring are identical to the original cell, DNA is replicated during the "S" phase of interphase so each cell contains the exact DNA. Eukaryotic Organism In oder for sexual reproduction to occur, cells must split into two so that each cell contains half the chromosomes as the parent. You have only two kinds of cells that split their chromosomes in half ( eggs and sperm). |
You first start of with diploid cells from both your mom and dad. It's different for humans and Dogs. Humans have 46 diploid cells as to where Dogs have 78 chromosomes.
|
From there you get half of the diploid cells from both parents which turn into haploid cells. You get 39chromosomes from the egg and 39 for the sperm.
|
Now you put the haploid cells together and turn it into a diploid cell. In order for it to be a diploid cell it has to have a total of 78 chromosomes so that you can have your final product.
