How do mitosis and meiosis differ among humans, chickens, and alligators?

Mitosis- produce two identical somatic daughter cells

Meiosis- produce four genetically different reproductive daughter cells.

Explanation:

Mitosis and meiosis are the two major cellular divisions in multicellular organisms. However, they differ in series of aspects.

Mitosis is a cell division that involves the production of two daughter cells which are genetically identical to the parent cell. Mitosis is used to multiply somatic cells, hence, it is called multiplication division. Mitotic process is the same in humans, alligators and chickens.

Meiosis, contrarily, is a cell division that involves the production of four daughter cells which are genetically different from the parent cell. Meiosis occurs in a two step division process in order to produce sex cells or gametes with a reduced number of chromosomes. Hence, meiosis is called reduction division. Note that, meiosis only occurs in reproductive cells. Meiotic process is likewise in humans, alligators and chickens as long as they reproduce sexually via gametes.
