Answer:
Before division → Original diploid cell → 2n = 6
After meiois → Four haploid cells → n = 3
Step-by-step explanation:
Through the process of meiosis, each diploid germinal cell produces four gametes, called sperm and egg cells, through the gametogenesis process.
The four gametes are the daughter haploid cells (n) produced from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of the chromosomes of the original one.
Meiosis completes in two phases: during the first phase occurs chromosomes reduction division, and in the second one occurs a new but not reductive division.
Gametes´destiny is to merge during fecundation, and a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell and suffers successive mitosis to form the new organism.
In the exposed example, there are six original chromosomes in the diploid germ cell. After meiosis, the original cell produced four haploid cells containing three chromosomes each.
- The 2n number is 6 in the original cell,
- After the division, haploid chromosomes number are left in each cell.
- The haploid number, n, is 3 in each daughter cell.
