Question

Fill in the blanks based on your knowledge of mitosis and meiosis.

1.
A human has 46 chromosomes in each body cell. How many chromosomes
would be found in its daughter cells after mitosis?
2.
A yeast cell has 32 chromosomes. How many chromosomes would be found in
its daughter cells after meiosis?
4
3. A fruit fly's gametes have
chromosomes, because its body cells have 4
chromosomes.
4. A kangaroo's somatic cells have 12 chromosomes, so that means its sex cells
have 6 chromosomes.
5. If cabbage plant has 9 chromosomes in its reproductive cells, then it means that
it has 18 chromosomes in its
cells.
6.
A fern has 600 chromosomes in its gamete cells. How many chromosomes
would be found in its regular body cells?

Answer 1

The number of chromosomes in daughter cells after mitosis depends on the original cell's chromosome count. In meiosis, the chromosome count is halved.

Step-by-step explanation:

1. A human has 46 chromosomes in each body cell. After mitosis, the daughter cells would also have 46 chromosomes, since mitosis results in the production of two identical daughter cells.

2. A yeast cell has 32 chromosomes. After meiosis, the daughter cells would have 16 chromosomes, since meiosis results in the halving of the chromosome number.

3. A fruit fly's gametes have 2 chromosomes, because its body cells have 8 chromosomes.

4. A kangaroo's somatic cells have 12 chromosomes, so that means its sex cells have 6 chromosomes.

5. If a cabbage plant has 9 chromosomes in its reproductive cells, then it means that it has 18 chromosomes in its somatic cells.

6. A fern has 600 chromosomes in its gamete cells. Regular body cells of a fern would also have 600 chromosomes, since the gametes are produced through meiosis, not mitosis.
