What else can I help you with?
Could crossing over occur during second meiotic division?
No, crossing over occurs during the first meiotic division when homologous chromosomes exchange genetic material. In the second meiotic division, the chromatids of each chromosome separate, resulting in the formation of haploid daughter cells.
What cell division produces cells?
Meiosis
Why the formation of chasmata is an important feature of meiotic division?
The formation of chiasmata during meiotic division plays a crucial role in genetic recombination. Chiasmata physically link the paired homologous chromosomes, allowing for the exchange of genetic material through crossing over. This process increases genetic diversity and contributes to the variation seen in offspring.
How do you identify the meiotic division that occurs in the Lilium anther?
In Lilium anthers, meiotic division can be identified by observing the formation of tetrads of microspores within the anther locules. These tetrads are the result of meiosis, where each microspore undergoes a reduction division to produce haploid cells. By examining the anther tissue under a microscope, the stages of meiotic division can be visualized.
Name two animal germ-line cells that can go through meiotic division?
Sperm cells in males and egg cells in females can go through meiotic division.
Why meiotic division is called reduction division?
Meiotic division is called reduction division because the daughter cells (called 'gametes') are haploid, that is, carry half the number of chromosomes of the parent cells. Gametes carry one chromosome of each homologous pair, whereas the diploid parent cells carry both.
Down syndrome is a genetic disorder caused by the presence of an extra chromosome in the body cells of humans this extra chromosome occurs in the gamete as a result of?
an error in meiotic cell division
Could crossing over occur during second meiotic division?
No, crossing over occurs during the first meiotic division when homologous chromosomes exchange genetic material. In the second meiotic division, the chromatids of each chromosome separate, resulting in the formation of haploid daughter cells.
Cells that undergo mitotic division but not meiotic division are called?
Somatic cells undergo mitotic division but not meiotic division. Meiotic division is only seen in germ cells to produce gametes.
When chromosomes fail to separate at either the first or second meiotic division this is known as?
When chromosomes fail to separate at either the first or second meiotic division, this is known as nondisjunction. Nondisjunction can lead to the formation of gametes with abnormal chromosome numbers, which can result in genetic disorders like Down syndrome.
Meiotic cell division occurs in a special organ known as?
Meiotic cell division occurs in the reproductive organs, such as the ovaries in females and the testes in males.
Meiotic cell division in animals is directly responsible for the?
Meiotic cell division in animals is directly responsible for the producing sex cells.
What cell division produces cells?
Meiosis
How does mitosis conserve chromosome number while meiosis reduces the number from diploid to haploid?
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.
Why is the second meiotic division necessary if the reproduction of chromosome number is accomplished by the first division?
You need the second step to further divide the chromosome into two halves. When that happens the sex cells will have half the chromosomes and when combined with the other sex cell that will produce an individual with one half from the father and one half from the mother.
What is it called when sex cells divide?
meiotic division
Why the formation of chasmata is an important feature of meiotic division?
The formation of chiasmata during meiotic division plays a crucial role in genetic recombination. Chiasmata physically link the paired homologous chromosomes, allowing for the exchange of genetic material through crossing over. This process increases genetic diversity and contributes to the variation seen in offspring.
