question 28
which of the following statements regarding mitosis and meiosis is false?

1. meiosis only occurs in the ovaries and testes.
2. body cells (somatic) undergo mitosis
3. mitosis produces daughter cells with half the number of chromosomes as the parent cell.
4. a normal human zygote has 46 chromosomes.

Explanation:

• Option 1: Meiosis occurs in the ovaries (to produce eggs) and testes (to produce sperm), so this statement is true.
• Option 2: Somatic (body) cells divide by mitosis for growth, repair, etc., so this statement is true.
• Option 3: Mitosis produces daughter cells with the same number of chromosomes as the parent cell. Meiosis produces daughter cells with half the number of chromosomes as the parent cell. So this statement is false.
• Option 4: A normal human zygote (formed by the fusion of sperm and egg) has 46 chromosomes (23 from sperm and 23 from egg), so this statement is true.

Answer:

1. Mitosis produces daughter cells with half the number of chromosomes as the parent cell.
