Answer:
d mitosis
Explanation:
In mitosis, cell division occurs, obtaining 2 daughter cells with the same genetic material in each of the cells that originated them. (same number of chromosomes as the stem cell)
<span>Artificial and natural selection are really the same process but one is driven by man and the other is driven by an organism's traits that allow them to survive and reproduce. Artificial selection is when mankind chooses certain traits in plants and animals and breeds to enhance that trait.</span>
The reduction in chromosome number occurs during <u>meiosis I.</u>
Chromosomes are long molecules of DNA that contain some or all of an organism's genetic material. In most chromosomes, very long, thin strands of DNA are coated with packaging proteins. In eukaryotic cells, the histones are the most important of these proteins.
Within the nucleus of all cells, DNA molecules are packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly wrapped many times around proteins called histones that support its structure.
Another type of cell division, meiosis, ensures that humans have the same number of chromosomes from generation to generation. This is a two-step process in which the number of chromosomes is halved from 46 to 23 to form sperm and eggs.
