What would happen if a cell went through mitosis instead of meiosis?

Answer 1

Cells formed by mitosis are exact copies of their parent cells, containing the same number of chromosomes. If sex cells were formed from mitosis, they would contain the same number of chromosomes as the somatic cells, instead of half, as they do through meiosis. Combining the egg and sperm in normal sexual reproduction would then produce an offspring with twice the chromosomes as its parent, making it a completely different organism, providing it survives at all. This process would continue with each new generation have twice the chromosomes as its parent.

Answer 2

The number of chromosomes would be diploid rather than haploid. For example, a human gamete produced by mitosis would have 46 chromosomes rather than 23. If this gamete were involved in fertilization, the resulting embryo would not survive.

Answer 3

During meiosis the number of chromosomes are matched into pairs (one from each parent) and then separated into two sets of one each - i.e the number of chromosomes is cut in half. In mitosis the chromosomes are replicated into double the usual number and then split into two identical sets - one for each new cell.

If the sperm and egg just did mitosis then each germ cell would have the full double set of chromosomes and then when they fused the resulting egg would have twice the normal number. With the number of chromosomes (and so the amount of DNA ) doubling every generation the species would not get far before the whole thing became untenable.

Answer 4

It normally happens in haploid cells and normal body cells.If sex cells do not undergo meioris chromoromal number would be doubled from generation to generation.And there will be no new characteristics.

Answer 5

each cell forms two new cells
