The answer is d.
Meiosis is a kind of cell division that produces daughter cells that are genetically different to parent cells and contains half number of chromosomes comparing to parent cells.
At the beginning, the parent cell duplicates its chromosomes just like mitosis. The cell divides and leads to 2 genetically identical daughter cells.
This is where mitosis ends. But in meiosis, the 2 cells produced divides again, but without duplicating it's chromosomes. Therefore, this leads to 4 daughter cells at the end, each with halved number of chromosomes.
When a cell has a halved number of chromosomes, it's said to be haploid.
This is usually common in gametes so that biodiversity can be achieved.
Therefore, the answer to this is d.
Answer:
The mutated cell will have 25 chromosomes.
Explanation:
Meiosis is a cell division process in sexual reproduction which involves two successive divisions of a cell having a diploid (2n) number of chromosomes into four daughter cells having a haploid (1n) number of chromosomes.
Meiosis consists of two successive nuclear divisions, meiosis I and meiosis II. Each division consists of these stages: prophase, metaphase, anaphase, and telophase.
Anaphase consists of anaphase I and II. During anaphase II, the centromeres linking the two pairs of chromosomes which are called chromatids separate, and the sister chromatids move toward the opposite poles of the cell and are now called chromosomes.
Therefore in the chimpanzee having 48 chromosomes, after underoing meiosis, each daughter cell will have 24 chromosomes. If there is a case of non-separation of one chromosome, the cell will have 1n + 1 chromosomes i.e. 24 + 1 = 25 chromosomes.
