Meiosis I is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are very similar to the phases preceding mitosis. The G 1 phase is focused on cell growth. The S phase is when the DNA of the chromosomes is replicated.
In meiosis, there are two rounds of nuclear division resulting in four nuclei and usually four daughter cells, each with half the number of chromosomes as the parent cell. The first separates homologous chromosomes, and the second separates chromatids into individual chromosomes.
In prophase I of meiosis I, the homologous chromosomes form the tetrads. In metaphase I, these pairs line up at the midway point between the two poles of the cell to form the metaphase plate. There is an equal chance the microtubule fiber encounters a chromosome from mom or dad.
However, there are two rounds of division in meiosis. Meiosis I is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are very similar to the phases preceding mitosis. The G 1 phase is focused on cell growth. The S phase is when the DNA of the chromosomes is replicated.
megaspore of ovule is the correct answer.
Complete answer:Meiosis IMeiosis IIThe number of products formed or cells produced is two.The number of products formed or cells produced is four.The parent cell is one diploid cell, and the daughter cells are two haploid cells.The parent cells are two haploid cells, and the daughter cells are 4 haploid cells.5 more rows
The result of meiosis is 4 gametes, or sex cells, that each contain half of the genetic information in the parent organism.
Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid. In humans, the products of meiosis are sperm or egg cells.
Meiosis ends in 4 haploid daughter cells(share similarities) and mitosis ends in 2 diploid sister cells (genetically identical).
Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
The result of meiosis is the formation of four unique cells, each carrying a new assortment of genes and chromosomes, and each with half the number of original chromosomes, thus maintaining the chromosome number of a species from generation to generation.
two identical daughter cellsThe result of mitosis is two identical daughter cells, genetically identical to the original cell, all having 2N chromosomes.
What is the end product of Mitosis? Two identical daughter cells.
The cells are haploid because at each pole, there is just one of each pair of the homologous chromosomes. Therefore, only one full set of the chromosomes is present. This is why the cells are considered haploid—there is only one chromosome set, even though each homolog still consists of two sister chromatids.
In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity.
These cells have to be haploid because when they combine, their chromosomes also combine to become diploid
The idea that Earth orbits the sun is referred to as ____ of the solar system, because of the scientist who first proposed it.
