Meiosis occurs because it provides a way for genetic variability, since it would be unfavorable for an organism's offspring to have the same weaknesses that it did, as opposed to binary fission or mitosis. In mitosis, the parent and daughter cell will be identical if no genetic mutations occur (which most cells have built-in self-repair mechanisms).
The advantage meiosis gives to sexually reproducing organisms is biodiversity. Meiosis is a chance for the individuals to shuffle the deck, so to speak, mixing up their genes so offspring can be produced that have traits somewhat different than the parents, grandparents, great grandparents. This way individuals which are more fit for the environment can be produced.
Organisms that reproduce sexually generally exhibit gametic meiosis. Organisms that reproduce through gametic meiosis are typically humans or even animals.
They reproduce through meiosis.
It must or cells would not be able to reproduce. Eukaryotic cells replicate by mitosis. Prokaryotic cells replicate via binary fission.
Meiosis is a process of cell division that produces gametes in organisms that sexually reproduce. A gamete having more than one complete set of chromosomes cannot be produced by meiosis.
Because male and female cross the age of 18 they are reproducing are sex
Organisms that reproduce sexually generally exhibit gametic meiosis. Organisms that reproduce through gametic meiosis are typically humans or even animals.
The process of meiosis.
meiosis
No, meiosis does not occur in all growing organisms. Meiosis is a specialized form of cell division that occurs in sexually reproducing organisms to produce gametes (eggs and sperm). Organisms that reproduce asexually, such as bacteria and some plants, do not undergo meiosis.
They reproduce through meiosis.
which have diploid number of chromosomes in somatic cells.
So organisms can procreate and actually fulfill their biological purpose to survive and reproduce. Meiosis is the process in which some organisms reproduce.
If meiosis did not occur in sexually reproducing organisms, the chromosome number would double in each generation. Sexual reproduction results in new combinations of genetic traits.
There will be no reproduction
Through Meiosis
It must or cells would not be able to reproduce. Eukaryotic cells replicate by mitosis. Prokaryotic cells replicate via binary fission.
