Short Answer: the [it appears] one, extra, cellular process that only Meiotic Cells possess is termed "Chromosome Reduction"; we have seen (elsewhere) that this process results in the reduction of Chromosome Number from the mitotic {somatic} 2N to the Meiotic {gametic} 1N.

Mitosis is a cell division process that produces two daughter cells with the same chromosome number as the parent cell, which is diploid in most cases. In contrast, meiosis involves two rounds of cell division to reduce the chromosome number from diploid to haploid, producing gametes with half the number of chromosomes.

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?
Crossing over: Homologous chromosomes exchange genetic material during meiosis I, leading to genetic recombination. Synapsis: Homologous chromosomes pair up to form tetrads, allowing for exchange of genetic material and ensuring proper segregation. Reduction division: The number of chromosomes is halved during meiosis I, resulting in the formation of haploid cells.
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.
Does meiosis produce cells with a diploid chromosome number?
no, it produce 4 genetically different haploid cells
What process produces haploid cells from a diploid cell?
Meiosis produces haploid cells from a diploid cell
Are the final cells in meiosis diploid or haploid?
Haploid
Does meiosis make haploid diploid cells?
haploid
Is meiosis haploid or diploid?
The parent cell is diploid. The daughter cells are 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! :)
Does meiosis make haploid or diploid cell?
Meiosis makes 4 genetically unique haploid cells. Mitosis makes 2 diploid cells.
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.
What is the process that results in 4 haploid gametes?
Meiosis results in four haploid cells known as gametes.
Are mitosis parent cells diploid or haploid?
Meiosis produces 4 haploid cells.
Which process goes from diploid to haploid?
Meiosis.
Why is meiosis described as a precess of reduction division?
Because the chromosomes are reduced from 2n to n. From diploid( sister chromatids ) to haploid ( one chromosome ).
