Question

If an organism had 20 chromosomes, how many chromosomes would the daughter cell have after mitosis? After meiosis?​

Answer 1

Answer:

$\boxed {\boxed {\sf Mitosis: 20 \ chromosomes}}$

$\boxed {\boxed {\sf Meiosis: 10 \ chromosomes}}$

★Explanation:

Mitosis and meiosis are both types of cell divisions, but they are different.

Mitosis

• cell division that results in
• daughter cells used for growth, repair, and development

The cells are genetically identical with the same number of chromosomes as the parent cell.

Meiosis

• cell divisions resulting in 4 daughter cells for sexual reproduction

The cells are genetically different and have half the number of chromosomes as the parent.

The organism has 20 chromosomes.

Mitosis: same number of chromosomes=20

Meiosis: half the chromosomes= 20/2= 10

• After mitosis, the daughter cell has 20 chromosomes.
• After meiosis, the cell has 10.
