How do you calculate diploid and haploid?
The "haploid number" is the number of chromosomes in a given organism's reproductive cell (i.e., either sperm or egg or similar, depending on the species) or it's the number of pairs of chromosomes in an organism. They are easier to count just before mitosis or during the interphase of meiosis. So put a cell under a microscope, make sure it is in the right phase of reproduction and count the little "X's".
How meiosis and mitosis different?
The basic difference is that mitosis results in the production of two daughter cells that are identical to the parent cell, whereas meiosis results in the production of 4 daughter cells that differ from the parent cell in chromosome number and genetic components. There are also differences in the stages that occur during each process.
Which of the following occurs in meiosis but not mitosis?
Meiosis is the division of the gametes(sex cells), haploid (n) Mitosis is cell division, diploid (2n) In meiosis, there are the similar cycles (prophase, metaphase, anaphase, and telophase), but there are two cycles of each (ex: prophase 1, prophase 2 ETC).
How is meiosis 2 different from mitosis?
very little difference
Differences of Parthenogenesis diploid and parthenogenesis haploid?
Parthenogenesis diploid produces offspring with two sets of chromosomes, similar to sexual reproduction, resulting in genetic variation. Parthenogenesis haploid produces offspring with only one set of chromosomes, leading to clones of the mother with no genetic diversity.
What is present when you compare the number and type of cells that result from mitosis and meiosis?
Meiosis results in 4 haploid daughter cells with only half the number of chromosomes as the original cell.Mitosis results in 2 diploid daughter cells with the same number of chromosomes as the original cell.meiosis 4 and mitosis 2In mitosis, the daughter cells (2 produced per cell division) contain 2 copies of each chromosome (similar to the parent cell before division)In meosis, the daughter cells (2 produced per cell division) contain only one copy of each chromosome (half the chromosomal content of the parent cell)Meiosis results in 4 haploid daughter cells with only half the number of chromosomes as the original cell.Mitosis results in 2 diploid daughter cells with the same number of chromosomes as the original cell.
How are are binary fission and mitosis similar how are they different?
they are different because Binary is a prokaryotic cell and mitosis is a eukaryotic.
Why are meiosis and mitosis similar?
Meiosis and mitosis are both processes involved in cell division. They both include stages such as prophase, metaphase, anaphase, and telophase. However, meiosis involves two divisions resulting in four genetically unique haploid cells, while mitosis involves one division resulting in two genetically identical diploid cells.
What are the similarities and differences between mitosis and meiosis with respect to function location in the organism and the chromosome number haploid or diploid of the daughter cells produced?
Mitosis produces two Diploid Cells while Meiosis produces four haploid cells. The purpose of Mitosis produces new body cells and does not allow for genetic variation, while meiosis allows genetic variation through multiple processes. Meiosis produces sex cells (sperm) , which are key in reproduction of multi-cellular organisms. Each new cell contains half of the number of chromosomes. Meiosis has 2 cellular divisions, while mitosis only has one. They are both necessary to support life, and they both produce Diploid cells in the first division. Also, from a similar topic in Yahoo Answers (Which has a much better explanation) : Mitosis is a type of cell division to produce 2 X genetically identical diploid (2n) cells for growth and repair. Mitosis occcurs in somatic cells (normal body cells. Prior to mitotic division DNA is replicated to produce two identical chromatids attached by a centromere. This is essential so that each new daughter cell formed receives one copy of each chromosome. (One division) Meiosis only occurs in the sex organs to produce 4 X haploid (n), genetically different, gametes for sexual reproduction. Meiosis consists of two divisions: Meiosis I halves the number of chromosomes to give 2 X haploid cells. Meiosis II doubles the number of cells to give 4 X haploid gametes. Two processes during meiosis I increase variation . In prophase I homomolgous chromosomes cross over at points called chiasmata and exchange genetic material. In metaphase I the chromosomes line up along the equator in pairs. This is called random assortment where maternal and paternal chromosomes are arranged at random. Both of these increase variation to produce four genetically different gametes at the end of meiosis II DNA replication only occurs once, before Meoisis I.
What cell has homologous chromosomes?
A diploid cell has homologous chromosomes. Diploid cells contain two sets of chromosomes, with one set inherited from each parent. The homologous chromosomes have similar genes in the same order, but may have different versions of those genes.
Meiosis II is similar to which process?
Meiosis II is identical to Mitosis. Meiosis is split into two stages, Meiosis I and Meiosis II. Meiosis I is similar to mitosis however the cells resulting from it have half as many chromosomes as the parent cell.
Why does meiosis involve two nuclear divisions rather than one as in mitosis?
Meiosis involves two nuclear divisions—meiosis I and meiosis II—because it is designed to produce haploid gametes from a diploid cell. The first division (meiosis I) separates homologous chromosomes, reducing the chromosome number by half, while the second division (meiosis II) separates sister chromatids, similar to mitosis. This two-step process ensures genetic diversity through recombination and independent assortment, ultimately resulting in four genetically distinct haploid cells.
