Which occurs more frequently in your body mitosis or meiosis?
Mitosis occur more frequently in our body. Basically mitosis occur when we get an injury or is an asexual type of reproduction. It occurs at the time of cell division and our cells need to divide often. While meosis is form of sexual reproduction and it does not occur quite often . Also, meiosis occurs more in men than in women. Look at it this way Mitosis splits once as meosis splits twice and they're not identical
In a human body give an example of a where mitosis may occur Give an example of where meiosis would occur?
Mitosis occurs in somatic cells to generate new cells for growth and repair throughout the body. For example, mitosis occurs in skin cells to replace old or damaged skin cells. Meiosis occurs in reproductive cells to produce gametes (sperm and eggs). For example, meiosis occurs in the testes to produce sperm cells in males and in the ovaries to produce egg cells in females.
Name the 2 forms of cell division?
Meiosis- cell division that produces gametes or sex cells for reproduction Mitosis- cell division that produces identical, "daughter" cells for things like skin regeneration or replacing dead cells.
When does independent assortment occur in mitosis?
Independent assortment does not happen in mitosis, it happens in meiosis. In metaphase I of meiosis, synapsed homologous chromosomes align independently of one another along the metaphase plate. That is to say, one aligning in a certain fashion has no effect on another aligning in a certain fashion. In mitosis, chromosomes are exact copies of the parental cell's and independent assortment is a method of achieving genetic variation, which does not happen in mitosis.
Genetic disorders can result when chromatids fail to separate properly. During with phase is this problem most likely to occur?
In general, nondisjunction can occur in any form of cell division that involves ordered distribution of chromosomal material.There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during metaphase going into anaphase of mitosis.mitosis

What is more common in humans meiosis or mitosis?
Mitosis occurs in our somatic cells and Meiosis occur in our reproductive cells, gametes Most of the time our body is under the influence of mitosis which replace the old and worn out cells with new one's whereas the Meiotic type of division occurs at a specific time in the life of an organism's development. The chromosome number in mitotic division remains the same whereas in meiotic division the chromosomes number is halved

What is the extra step in meiosis than mitosis?
In mitosis the chromosomes duplicate and the cell splits apart. But in meiosis, the cell does the same thing but this time, the daughter cells split again without duplicating the chromosomes. This causes those cells to have only half the amount of chromosomes. Hope i helped!
Why does meiosis result in more genetic variation than mitosis?
It would be wrong to consider mitosis insignificant as it helps in cell repair and replacement in our daily life and it would be impossible to survive without it and asexual reproduction as well but if it weren't for meiosis, none of us would have been born :) Meiosis is responsible for the division for our gamete cells which leads to the formation a zygote. from there on mitosis takes over.

Meiosis- cell division that produces gametes or sex cells for reproduction Mitosis- cell division that produces identical, "daughter" cells for things like skin regeneration or replacing dead cells.
Which happens first mitosis or cell division?
Mitosis was first discovered and meiosis evolved out of mitosis. Mitosis stands for the first division of a cell into two genetic identically cells. Meiosis stands for two divisions into four genetic different cells.
At what time does mitosis occur in the human body?
Mitosis a process more simply explained as regeneration of cells, as it is most significant in that process. The cells of our body replicate (clone themselves) as needed. For instance, if you cut your hand, the skin cells will regenerate in the process of mitosis, and so will all cells, except those of reproductive cells which use meiosis. To answer your question: our skin endures micro damage all the time and as regeneration is performed in mitosis, it also occurs all the time.
How does the number of chromosomes of a daughter cell produced through meiosis compare to one produced through mitosis?
Other than that, there's essentially nothing different immediately after cell division.Cells produced by mitosis will then continue with the cell cycle, duplicating their DNA, etc. Cells produced by meiosis will differentiate into full gametes, sperm for males, eggs for females, and maintain their haploid DNA.
When does independent assortment occur in mitosis?
Independent assortment does not happen in mitosis, it happens in meiosis. In metaphase I of meiosis, synapsed homologous chromosomes align independently of one another along the metaphase plate.

In mitosis, chromosomes are exact copies of the parental cell's and independent assortment is a method of achieving genetic variation, which does not happen in mitosis.
How many times does cytokinesis occur in meiosis?
Cytokinesis occurs twice in meiosis, once after Meiosis I and again after Meiosis II. Each time, it divides a cell into two daughter cells.
