Is there an S phase after meiosis 1?
No, there is no S phase after meiosis 1.
Does the nucleus divide in meiosis 1 and again in meiosis 2?
No, the nucleus does not divide in meiosis 1 and then again in meiosis 2. In meiosis 1, the nucleus divides once to reduce the chromosome number in the cell, resulting in two daughter cells. In meiosis 2, the two daughter cells from meiosis 1 divide again to form a total of four haploid daughter cells.
How does meiosis 1 differ from mitosis in terms of the process of cell division?
In meiosis 1, the cell divides twice to produce four daughter cells with half the number of chromosomes, while in mitosis, the cell divides once to produce two daughter cells with the same number of chromosomes as the parent cell.
How does metaphase 1 differ from metaphase of mitosis?
In metaphase I of meiosis, homologous chromosomes align at the cell's equator in pairs, while in metaphase of mitosis individual chromosomes align. Additionally, in meiosis I, genetic recombination and crossing over can occur between homologous chromosomes, increasing genetic diversity.
How do meiosis and sexual reproduction fertilization produce offspring that differ genetically from the parents?
Meiosis maintains genetic diversity in two ways:1) Genetic recombination: the exchange of genetic material between sister chromatids2) By random assortment of paternal and maternal chromosomes and the alleles of genes they contain.
How do meiosis 1 differ from those of meiosis 2?
Anaphase of Meiosis 1 separates the homologous chromosome pairs, but during Anaphase of Meiosis 2, the sister chromatids are separated instead. Also, Meiosis 1 starts with one diploid cell and ends with 2 haploid cells, whereas Meiosis 2 starts with the 2 haploid cells and ends with 4 haploid cells (gametes).
What happens in meiosis 1 that does not happen in meiosis 2?
DNA is copied in meiosis 1.
What are the two distinct stages of meiosis?
Meiosis I and meiosis II
What are the divisions of meiosis called?
Meiosis 1 and Meiosis 2
How long does the lining up of chromosomes during metaphase 1 of meiosis differ from the way they line up during metaphase of mitosis?
3 weeks
What are 2 distinctive divisions of meiosis?
Meiosis 1 and Meiosis 2
Is there an S phase after meiosis 1?
No, there is no S phase after meiosis 1.
What happens in meiosis that does not happen in meiosis 2?
DNA is copied in meiosis 1.
How many divisions occur in meiosis?
Meiosis does in fact divide twice, once in meiosis I (cytokinesis) and meiosis II (cytokinesis) basically it divides into four daughter cells at the end of meiosis. Two from meiosis I and four in meiosis II
Does the nucleus divide in meiosis 1 and again in meiosis 2?
No, the nucleus does not divide in meiosis 1 and then again in meiosis 2. In meiosis 1, the nucleus divides once to reduce the chromosome number in the cell, resulting in two daughter cells. In meiosis 2, the two daughter cells from meiosis 1 divide again to form a total of four haploid daughter cells.
How does meiosis 1 differ from mitosis in terms of the process of cell division?
In meiosis 1, the cell divides twice to produce four daughter cells with half the number of chromosomes, while in mitosis, the cell divides once to produce two daughter cells with the same number of chromosomes as the parent cell.
Does meiosis double the parental chromosomes number?
Meiosis 1
