Answer 1

1. C

2. D

3. D

4. B

5. A

Step-by-step explanation:

1.) - Meiosis is a kind of cell division that produces four daughter cells whose chromosome number has reduced by half. In other words, meiosis reduces the chromosome number of daughter cells by half i.e. diploid (2n) to haploid (n).

- On the other hand, mitosis produces two daughter cells that possess the same number of chromosomes as the parent cell. That is, a diploid (2n) parent will produce diploid (2n) daughter cells.

2.) Meiosis occurs in a two step division process known as meiosis I and meiosis II. Each division is made up of stages namely: prophase, metaphase, anaphase and telophase. However, a unique process called CROSSING OVER, occurs in the prophase I of the meiotic process when homologous chromosomes lie in pairs in a process called SYNAPSIS.

3.) The process of crossing over, which only occurs during meiosis, makes the possibility of genetic recombination occuring in sexually reproducing organisms high.

4.) Via the process of crossing over, meiosis aids to promote genetic diversity among species of organisms.

5.) Mitosis only occurs in somatic or body cells, hence, produces daughter cells that are exact replica of the parent cell. The daughter cells are identical in allele combination and number of chromosomes i.e. diploid cell (2n) produce diploid daughter cells (2n). Hence, it is false that mitosis produces haploid cells.
