Answer:
It occurs in organisms because an organism with a beneficial trait/mutation have a higher chnace of surviving compared to organisms that do not. So the organsims that do survive pass on their genes to the next generation, and the bext generation will pass on those genes to the generation after and so on. But all the organisms that do not possess a beneficial trait/mutations will not survive, therefore they cannot reproduce and pass on those genes to their offspring. This means that most of the population will posses that trait/mutation.
Example: Spotted moths camouflage with bark so they are seen by predators and eaten. Black moths are easily seen by predators and are eaten. Spotted moths then pass on their genes to the next generation of moths.
Similarities: Mitosis and meiosis both involve cell replication. They both involve prophase, metaphase, anaphase, and telophase.
Differences: Meiosis creates gametes while mitosis creates somatic cells. Mitosis creates two daughter cells, while meiosis creates four sperm cells in men and one egg cell and three polar bodies in women. Mitosis involves one round of cell division, while meiosis involves two. Mitosis creates cells that have the same number of chromosomes as the original cell, while meiosis creates cells that have half the number of chromosomes as the original cell.
Hope that helped you.
P.S. There are more similarities and differences, challenge yourself and see if you can find them! Good luck.
