Meiosis is a type of cell division in which the number of chromosomes is reduced by half. … These cells eventually differentiate into mature sperm or egg cells. During meiosis, homologous chromosomes separate, and haploid cells form that have only one chromosome from each pair.
What is the difference between mitosis and meiosis ck12?
meiosis: Process in cell division that reduces the chromosome number in order to make gametes. mitosis: Process in cell division during which the nucleus divides so that a new cell is produced that is identical to the parent cell.
What is meiosis cell division Short answer?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. … Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.
What are the two main purpose of mitosis and meiosis?
The purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells.
Why is crossing over important?
This process, also known as crossing over, creates gametes that contain new combinations of genes, which helps maximize the genetic diversity of any offspring that result from the eventual union of two gametes during sexual reproduction.
What is the difference between meiosis 1 and meiosis 2?
There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced.
