It reduces half the number of chromosomes because its spliting up a cell and that also splits into to parts. The most chromosomes human can have is 46 so ya. UNICORNS R AWESOME AND SO IS JOEY GRACEFFA

∙ 11y agoIn meiosis, DNA replicates once, but the nucleus and cell divide twice. This results in four haploid daughter cells, each having one set of chromosomes, as opposed to the body cells which have two sets of chromosomes.

∙ 11y agoThe chromosome number is reduced by half during meiosis because meiosis forms the gametes, egg and sperm cells, which will unite to form a new individual. For example, human egg and sperm cells each have 23 chromosomes, so that when the sperm fertilizes the egg, the new cell that forms will have 46 chromosomes, and is the first cell of the new individual (offspring).

What happens to the chromosome numbers during meiois?
During meiosis, the chromosome number doubles because the cells replicate their DNA and split into two cells in meiosis I and in meiosis II, they replicate DNA and split once again, to form four cells.
What is being reduced during the reduction division of meiosis?
Meiosis IS the process wherein the 'chromosome number' is reduced ... by one-half. This is the result of the separation of the two chromosomes of each of the chromosome pairs and the 'packaging' of each daughter chromatid into what are called 'Daughter cells'.
What happens in meiosis during telophase II?
A total of four daughter cells form. *apex*
What event occurs in an organism when a chromosome is not copied correctly during meiosis?
a mutation can happen.
What happens during metaphase in meiosis?
chromosomes move to the middle of the cell. mitotic spindles from the centrioles attach to the centromere of the chromosome
What happens to the chromosome numbers during meiois?
During meiosis, the chromosome number doubles because the cells replicate their DNA and split into two cells in meiosis I and in meiosis II, they replicate DNA and split once again, to form four cells.
Are the chromosome copied before meiosis or during meiosis?
before
The chromosome number is reduced from diploid to haploid during what?
meiosis I is reduction, meiosis II is division.
During meiosis the chromosome number does what?
During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.
What does the chromosome number do during meiosis?
During meiosis, the chromosome number decreases by half. For example, if a human cell with 46 chromosomes were to undergo meiosis, the result would be four daughter cells with 23 chromosomes in each.
How does the significance of meiosis maintained the chromosome number?
No. Meiosis results in halving of chromosome number. Chromosome number after one round of meiosis is half that of original chromosome number. Generally, meiosis takes place during gamete formation. So when two gametes fuse, they lead to restoration of the chromosome number. Hence chromosome number can be maintained in sexually reproducing organisms.
Crossing over occurs during which phase of meiosis?
Crossing over occurs during Prophase I of meiosis.
If a cell that undergoes meiosis later is four cells with chromosome numbers 17 17 18 and 16 what happened?
one of the sister chromatids in one of the two cells that was produced during the first division of meiosis did not separate during the second division resulting in one cell with an extra chromosome and one with a missing chromosome. This process is known as nondisjunction
What happens during meiosis that results in a defect characterized by the deletion of a chromosome?
what happens during meiosis that results in a defect characterized by the deletion of chromosomes
What are the Two strands of chromosome that become visible during meiosis or mitosis?
chromatid
What is it called when a change in the chromosome during meiosis occurs?
This change is know as polyploidy.
During meiosis sex cells form when chromosome pairs are what?
doubled
