Chromosomes do not exchange genetic material is not true meiosis. In the meiosis there are new combinations of genetic material in each of the four daughter cells
- These new combinations are the result of exchange of DNA between paired chromosomes.
- A single cell divides twice during the meiotic process to produce four haploid daughter cells.
- The gametes, eggs in females and sperm in male are these cells. Meiosis is broken down into two stages. Several phases are split into each step.
- For many sexually reproducing organisms, meiosis is required to maintain the same number of chromosomes in the progeny as in the parents. Two cells joining forces to form a new zygote is a component of fertilisation.
- There will be 4 copies of each gene in the progeny if the number of alleles for each gene is not reduced to 1 in the gametes that create the zygote. This would result in several developmental abnormalities in many species.
