How Many Haploid Cells Are Produced If Three Cells Undergo Meiosis?

February 14, 2024

One cell undergoing meiosis gives rise to four haploid cells. So if three cells undergo meiosis then it will produce a total of 12 haploid cells.

Haploid cells are produced through a process known as meiosis, a specialized type of reductional cell division that produces genetically distinct haploid gametes (eggs and sperm) from a diploid parent germ line cell. The first round of meiosis, called meiosis I, produces two unique daughter cells, each with half the number of chromosomes of the original diploid germ line cell. The second round of meiosis, meiosis II, then produces four haploid daughter cells, each with one copy of each pair of chromosomes.

During the S-phase of meiosis, the newly replicated chromosomes pair up in a process called synapsis. The paired chromosomes then swap some of their genetic material with each other, a process called crossing over. This process creates new combinations of genes in each daughter cell that are not present in either of the parent cells. These new combinations of genes give rise to sperm and egg cells, which can then produce offspring through sexual reproduction.

Once the chromosome pairs have been separated, they can then be joined to each other again by the centromere. The spindle then contracts and pulls the sister chromatids to opposite ends of the cell. This leaves each daughter cell with one chromosome from each homologous pair, but still joined to its sister chromatid. Each daughter cell is now known as a haploid gamete, and it has 23 chromosomes in total.
