Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. Both produce two daughter cells from each parent cell.
Which part of meiosis 1 or 2 is most similar to mitosis?
Meiosis II is most similar to mitosis as in meiosis II it is the centromere between two sister chromatids which lines up on the metaphasal equator and not the chiasma joining two homologous chromosomes as in meiosis I.
Is meiosis 1 and meiosis 2 the same?
There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced.
Why is meiosis 2 necessary?
The cells are diploid, therefore in order to distribute the chromosomes eqully among the daughter cells so that they contain half the chromosome , Meiosis II is necessary. … It reduces the chromosome number to half so that the process of fertilisation can restore the original number in the zygote.
Why interphase between meiosis I and meiosis II is short?
Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. Hence between meiosis I and meiosis II , there is no interphase.
What are 3 similarities and 3 differences between mitosis and meiosis?
Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
What are the similarities and difference between mitosis and meiosis Brainly?
Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis. … Daughter cells resulting from mitosis are diploid, while those resulting from meiosis are haploid.
What are major differences between mitosis and meiosis?
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
