What else can I help you with?
The complete set of genetic material in an organism is called its?
Short Answer is It's Chromatin. Ordinarily it is called Diploid, see chromosome pairs, the chromosome number is 2N. After meiosis the genetic material is Haploid, its chromosome number is 1N; after replication yet before mitosis the genetic material is Quadraploid with its chromosome number 4N - briefly. The full set of genetic material in an organism is called GENOME.
Describe three events that occur during meiosis 1 but not during mitosis?
1.Synapsis and crossing over in prophase I: Homologous chromosomes physically connect and exchange genetic information 2.At the metaphase plate, there are paired homologous chromosomes (tetrads), instead of individual replicated chromosomes 3.At anaphase I, it is homologous chromosomes, instead of sister chromatids, that separate
What is the product of meiosis l?
The product of meiosis I is two daughter cells, each containing half the number of chromosomes as the original parent cell. These daughter cells are genetically different from each other and from the parent cell due to the process of genetic recombination that occurs during meiosis I.
What phase of meiosis do homologous chromosomes cross over?
Crossing over begins early in prophase I of meiosis. At the time, homologous chromosomes Are paired along their lengths. Each gene on one homologue ia alined precisely with the corresponding gene on the other homologue. Source: my science book copy right 2006
Do chromosomes double in mitosis?
No, chromosomes do not double in mitosis. Instead, the existing chromosomes are replicated during the S phase of the cell cycle, resulting in two identical sister chromatids for each chromosome. During mitosis, these sister chromatids are separated to form two new daughter cells with the same number of chromosomes as the parent cell.
What is another name for meiosis because the number is reduced from haploid to diploid?
Another name for meiosis, which results in the reduction of chromosome number from diploid to haploid, is reduction division.
Dose meiosis produce diploid or haploid cells?
its haploid= 4 cellsBy the end of meiosis all four resulting daughter cells are haploid.
How can you tell if a sperm cell is in meiosis 1 or meiosis 2?
To determine if a sperm cell is in meiosis I or meiosis II, you can look at the chromosome number and structure. In meiosis I, homologous chromosomes are separated, resulting in cells with a diploid (2n) chromosome number, where each chromosome still consists of two sister chromatids. In contrast, during meiosis II, sister chromatids are separated, resulting in haploid (n) cells, where each chromosome consists of a single chromatid. Therefore, if you observe a cell with a diploid chromosome number, it is in meiosis I; if it has a haploid number, it is in meiosis II.
Chromosome number that results from meiosis is called?
Meiosis reduces the number of chromosome sets from two (diploid), to one (haploid). In mitosis the daughter cells are genetically identical to the parent cell, but meiosis produces cells that differ genetically from the parent cell as well as each other. In the final stage of meiosis II there end up being 4n daughter cells. So remember mitosis is diploid and meiosis is haploid.
Is the parent cell in meiosis haploid or diploid?
The parent cell in meiosis is diploid.
Are daughter cells in meiosis haploid or diploid?
Daughter cells in meiosis are haploid.
Are the cells produced after meiosis I haploid or diploid?
The cells produced after meiosis I are haploid.
How are the cells at the end of meiosis different from the cell at the beginning of meiosis use the term chromosome number haploid and diploid in your answer?
At the beginning of meiosis, the cell is diploid, meaning it contains two sets of chromosomes (one from each parent). After two rounds of division in meiosis, the resulting cells are haploid, containing only one set of chromosomes. This reduction in chromosome number is crucial for sexual reproduction, as it ensures that when fertilization occurs, the diploid state is restored in the zygote. Thus, the cells at the end of meiosis have half the chromosome number compared to the original diploid cell.
Does mitosis create haploid nuclei?
No. Haploid cells/nuclei can only be created in meiosis.
Are the final cells in meiosis diploid or haploid?
Haploid
Does meiosis make haploid diploid cells?
haploid
If a diploid cell with 8 chromosomes goes through meiosis how many chromosome will the resulting haploid cells have?
It would have 4, because HAPloid means half. So whatever the diploid has the haplois will have HALF of that! :)
