How many chromosomes will each nucleus have meiosis 1?
THe number of chromosomes in a nucleus depends on the species. In humans each nucleus has 23 pairs of chromosomes so there are 46 chromosomes total.
The division of the nucleus in reproductive cells is called?
The division of the nucleus in reproductive cells is called meiosis. Meiosis is a type of cell division that results in four daughter cells with half the number of chromosomes as the parent cell, necessary for sexual reproduction.
What Meiosis occurs in .?
meiosis occurs in the overies and the testies.....there is 2 stage of meiosis...meiosis 1 and meiosis
What is formed a the end of meiosis?
In meiosis diploid cells divide to produce four daughter cells each of which is haploid. It is the type of cell division required to produce gametes.
Recombination occurs during?
meiosis
Does the nucleus disappear during mitosis and meiosis?
No, the nucleus does not disappear during mitosis or meiosis. It undergoes changes in structure and organization, such as condensation of the chromatin into visible chromosomes, but the nucleus remains present throughout these processes to ensure proper segregation of genetic material.
How many divisions occur in meiosis?
Meiosis does in fact divide twice, once in meiosis I (cytokinesis) and meiosis II (cytokinesis) basically it divides into four daughter cells at the end of meiosis. Two from meiosis I and four in meiosis II
How is the chromosome number reduced between meiosis 1 and meiosis 2?
In spermatogenesis, the cell first replicates from 46 to 92, then divides in meiosis 1 to 46-46 then again in Meiosis 2 to form 23-23-23-23 which are 4 daughter spermatids. In oogenesis the cell replicates from 46 to 92, then divides in meiosis 1 to 46-46 then again in Meiosis 2 to form 23-23-23-23 which are 1 egg and 3 polar bodies
1.125 as a fraction?
1 1/8 125/1000 divide by 5 25/200 divide by 5 again 5/40 divide by 5 again 1/8 OR just divide by 125.
How many chromosomes will each nucleus have meiosis 1?
THe number of chromosomes in a nucleus depends on the species. In humans each nucleus has 23 pairs of chromosomes so there are 46 chromosomes total.
What does not Happen between meiosis 1 and mesios2 that pervents chromosomes from replicating again?
nondisjunction
The division of the nucleus in reproductive cells is called?
The division of the nucleus in reproductive cells is called meiosis. Meiosis is a type of cell division that results in four daughter cells with half the number of chromosomes as the parent cell, necessary for sexual reproduction.
Which has two divisios meiosis or mitosis?
Meiosis has two divisions, called meiosis I and meiosis II. Meiosis I involves separating homologous chromosomes, while meiosis II involves separating sister chromatids. Mitosis, on the other hand, only has one division where the goal is to produce two daughter cells with identical genetic information to the parent cell.
Can sperm be produced with meosis 1 or 2?
Sperm production involves meiosis, which consists of two divisions: meiosis I and meiosis II. Meiosis I reduces the chromosome number, while meiosis II separates sister chromatids, resulting in haploid sperm cells with half the number of chromosomes as the parent cell.
What happens in meiosis 1 that does not happen in meiosis 2?
DNA is copied in meiosis 1.
What are the two distinct stages of meiosis?
Meiosis I and meiosis II
Meiosis consists of two cell divisions what are they?
Meiosis consists of two cell divisions: meiosis I and meiosis II. Meiosis I separates homologous chromosomes, while meiosis II separates sister chromatids. This process ultimately produces four haploid daughter cells.
