What is the importance of meiosis in living things?

Answer 1

Mitosis was the norm until Meiosis (two sexes) evolved 580 Million Years Ago.

Each Cell produced has exactly half of the information of each of the Cells it came from, meaning, each Cell has half of the characteristics its "parent" had.

Answer 2

• Meiosis is NOT the PROCESS of reproduction. That would be intercourse if we are talking about sexually reproducing organisms. (i.e. humans, deer, fish, dogs, cats, horses, etc.) For prokaryotic cells it is called binary fission, which produces a clone and has the need of only one parent/mother cell. In eukaryotic cells it is MEIOSIS and MITOSIS.
• Meiosis is the reduction division in which the diploid (2n) number of chromosomes is reduced to haploid (n) during gamete formation. (or spore formation)
• Meiosis is important to all living things, because if our cells (during gamete formation) did not undergo this process then we would all be much more alike. This trait helps us humans to be diverse and helps us as a species to adapt to our environment faster and more efficiently.

Answer 3

Meiosis is important because it allows for a larger amount of genetic diversity than mitosis does. If you have two organisms combining their genes as opposed to just making a copy of yourself with the occasional mutation, the species with meiosis would be more likely to survive and differentiate, maybe become more complex.

Answer 4

Meiosis is the process by which organisms reproduce. It is also the source of genetic variation within species. Meiosis is the process by which organisms continue on from generation to generation

Answer 5

Meiosis is important to the variety of life because, during meiosis, it combines the DNA of two different people.Without it, we would be the same person over and over and over again. Therefore, meiosis is important because it creates variety of life, so that we are not just copies of our dad or mom.

Answer 6

In meiosis, four daughter cells each having half the amount of chromosomes of the original parent cell are produced. Each new cell has different chromosomes so each cell is different. As a result, if these cells are used for reproduction, each reproduced organism will also be different creating variation in the population.

Answer 7

Meiosis ensures that the ploidy (the number of copies of the genetic material) remains constant from generation to generation. During reproduction, the fusion of the gametes would give a copy number which would be the sum of the genetic material arriving from each parent. By meiosis, each parent's genetic material is made haploid (single copy) so that they can fuse together to become diploid (two copies).

The process of crossing over during meiosis results in to new genetic combinations to create genetic variations. Useful genetic variations result in better genotypes which are helpful in evolution.

Answer 8

Meiosis is important because it is the process by which sex cells (sperm and egg) are formed, allowing for genetic diversity in offspring. It also helps maintain the constant number of chromosomes in a species, as it halves the chromosome number during cell division. Additionally, meiosis promotes genetic variation through processes like crossing over and independent assortment.

Answer 9

No meiosis, no new cells.
