Meiosis produces four haploid daughter cells, called gametes. Haploid means that each cell has half the chromosomes of the original parent cell.
In humans, all four of the male gametes produced by mitosis are sperm cells. However, in females only one of the four daughter cells becomes an ovum/egg.
What else can I help you with?
Could crossing over occur during second meiotic division?
No, crossing over occurs during the first meiotic division when homologous chromosomes exchange genetic material. In the second meiotic division, the chromatids of each chromosome separate, resulting in the formation of haploid daughter cells.
Which of the two meiotic divisions is similar to the first mitotic division?
Yes, in that the sister chromatids of the homologous chromosomes separate into four new daughter cells. However, the result is four genetically non-identical daughter cells with only one set of 23 chromosomes.
What do you get from meiosis that you don't get from mitosis?
Mitotic cell division produces two genetically identical daughter cells that are genetically identical to their parent cell. The daughter cells that result from mitotic cell division are 2n, having two sets of chromosomes. Meiotic cell division produces four genetically non-identical cells that are 1n, having only one set of chromosomes. The parent cell for meiotic cell division is 2n.
What cell division produces cells?
Meiosis
The second meiotic division is essentially a mitotic division except for the fact that the cells produced are?
Haploid instead of diploid. This means they have half the number of chromosomes compared to the original cell.
What is the process for making sex cells with half the number of chromosomes?
meiotic cell division
Cells that undergo mitotic division but not meiotic division are called?
Somatic cells undergo mitotic division but not meiotic division. Meiotic division is only seen in germ cells to produce gametes.
Why are germ cells diploid prior to their first meiotic division?
Germ cells go through DNA replication during interphase before their first meiotic division. This results in them being diploid, with two sets of chromosomes, in order to ensure genetic diversity in the resulting haploid daughter cells produced after meiosis.
Could crossing over occur during second meiotic division?
No, crossing over occurs during the first meiotic division when homologous chromosomes exchange genetic material. In the second meiotic division, the chromatids of each chromosome separate, resulting in the formation of haploid daughter cells.
Is disploid the second stage of meiotic division?
No, "disploid" refers to a state where an organism has two sets of chromosomes. Meiotic division is a process that produces gametes with half the number of chromosomes, known as haploid cells. So, disploid is not the second stage of meiotic division.
A meiotic division produces how many daughter cells?
A meiotic division produces four daughter cells.
How would you distinguish human mitotic cells from human meiotic cells?
Human mitotic cells undergo cell division to produce two identical daughter cells with the same number of chromosomes as the parent cell. In contrast, human meiotic cells undergo two rounds of cell division to produce four haploid daughter cells with half the number of chromosomes as the parent cell. Meiotic cells are involved in the formation of gametes (sperm and egg cells) for sexual reproduction, while mitotic cells are involved in growth, repair, and asexual reproduction.
Number of chromosomes in daughter cells formed by first division?
The number of chromosomes in daughter cells formed by the first division is the same as the parent cell, typically 46 chromosomes in humans. This is because during the first division, chromosomes are replicated and then distributed equally between the daughter cells.
Which of the two meiotic divisions is similar to the first mitotic division?
Yes, in that the sister chromatids of the homologous chromosomes separate into four new daughter cells. However, the result is four genetically non-identical daughter cells with only one set of 23 chromosomes.
What do you get from meiosis that you don't get from mitosis?
Mitotic cell division produces two genetically identical daughter cells that are genetically identical to their parent cell. The daughter cells that result from mitotic cell division are 2n, having two sets of chromosomes. Meiotic cell division produces four genetically non-identical cells that are 1n, having only one set of chromosomes. The parent cell for meiotic cell division is 2n.
Why meiotic division is called reduction division?
Meiotic division is called reduction division because the daughter cells (called 'gametes') are haploid, that is, carry half the number of chromosomes of the parent cells. Gametes carry one chromosome of each homologous pair, whereas the diploid parent cells carry both.
What cell division produces cells?
