How are haploid and diploid related to mitosis and meiosis?
Meiosis in simple terms is the process by which gametes (sperm and egg) fuse together to produce a fertilised egg. Haploid is a word that refers to how many chromosomes a certain cell has. In this case the gametes have a haploid number of chromosomes, which is half the number a normal cell has. A normal cell has a diploid number of chromosomes. So in meiosis the two gametes come together with their hapoid number of chromosomes each to create an egg that has a diploid (standard) number of chromosomes.
How does independent orientation of chromosome during meiosis increase genetic variation?
Independent orientation of chromosomes refers to the allignment of the homologous chromosomes along the metaphase plate in metaphase I of meiosis. As the pair of chromosomes line up, one inherited from your mother and the other from your father, there are two orientation possibilities of equal probability; each pole has a 50% chance of inheriting one or the other. This is best explained using the sex chromosomes. Males are XY and females are XX. To differentiate these two female X chromsomes, we will call them Xa and Xb. In Metaphase I of meiosis, the chromosomes can be lined up along the metaphase plate (represented as l) as follows: Male: X l Y or Y l X Female: Xa l Xb or Xb l Xa
What n value are mitosis cells?
n number refers to number of chromosomes. As you know, one set of your chromosomes come from mom and one set from dad. This is the 2n condition. This condition is maintained in mitosis, as all chromosomes double and two daughter cells are formed having the complete 23 pairs, 46 chromosomes of the 2n condition. Meiosis, which means ' halving ', doubles all chromosomes which are from dad to dad and mom to mom sister chromatids. These cross over genetic material with each other and the mom to mom set and the dad to dad set are pulled to opposite poles and two daughter cells are formed. Now, phase two of meiosis begins and the pairs in each daughter cell are pulled to opposite poles and you end up with four cell with 23 chromosomes apiece in them. This is the n condition.
Haploid cells are symbolized by what?
Haploid cells are denoted n, and diploid cells are denoted 2n."n" refers to the set of chromosomes - therefore haploid cells have one set of chromosomes and diploid cells have two sets (pairs of chromosomes). Haploid cells have half the number of chromosomes as diploid cells.
What are three things that refers to gene?
DNA Chromosomes Protiens
What is the ploidy of animal cells that are capable of meiosis?
Ploidy refers to the number of sets of chromosomes in an organism. The ploidy of animal cells that are capable of meiosis is diploid.
In mitosis or meiosis do doubled chromosomes pair to form tetrads?
Tetrads form during meiosis. Tetrad refers to the four chromatids of homologous chromosomes.These are present during Prophase.
What is the process that results in 4 haploid gametes?
Meiosis results in four haploid cells known as gametes.
How are chromosomes in a cell at metaphase of mitosis similar to and different from the chromosomes in a cell at metaphase of meiosis 2?
Mitosis refers to the division of cells , so it goes from haploid to diploid (increases). Meiosis on the other hand refers to the division of gametes (sexual reproductive cell such as an egg or sperm), so it goes from diploid to haploid (decreases). Since meiosis, has an e just remember this one refers to the sexual reproduction of cells. Mitosis creates 2 identical cells and meiosis creates 4 different cells (each one contain half of the original content). Meiosis involves in sexual reproduction whereas mitosis involves in asexual reproduction.

How many chromatids per chromosome exist following anaphase 2?
Meiosis refers to a type of cell division that results in 4 daughter cells. In meiosis II, there is only 1 chromatid per chromosome that exists following anaphase II.
What does n and 2n means?
2N Refers to a diploid cell or organism, in which two copies of each gene are present. Cells before and after mitosis are 2N, or diploid. Cells before meiosis are 2n, and following meiosis are 1n, or haploid.
What he meaning haploid?
Haploid refers to having a single set of chromosomes.Haploid refers to having a single set of chromosomes.
What happens to a 2n cell during meiosis?
2n in cytoplasm refers to the diploid number of chromosomes in a cell. Diploid means that two sets of chromosomes are present in the cytoplasm. In humans the diploid number is 46 chromosomes. This means that in human cells the 2n in cytoplasm is 46. In other organisms the 2n in cytoplasm can vary. For example: In fruit flies the 2n in cytoplasm is 8. In nematodes the 2n in cytoplasm is 6. In wheat the 2n in cytoplasm is 42.The 2n in cytoplasm can be used to distinguish between haploid and diploid organisms. Haploid organisms such as yeast have only a single set of chromosomes in the cytoplasm. Diploid organisms such as humans have two sets of chromosomes in the cytoplasm.
