Yes, meiosis reduces the number of chromosomes in a cell by half, resulting in cells with haploid chromosome number. This is essential for sexual reproduction to produce gametes with half the genetic material of the parent cells.
Meiosis is the way sex cells are produced. Each sex cell (in a human) has 23 chromosomes, so if you like, meiosis reduces the number of chromosomes in the cell by a half. A better way of putting this is when the producing cell divides, it splits its chromosomes into two, passing one half onto each new cell, rather than replicating itself.
No, the new cells have the exact number of chromosomes as the parent cells in mitosis.

Meiosis reduce the number of chromosomes by?
Meiosis reduces the number of chromosomes by half. This is essential for sexual reproduction, as it ensures that when gametes (sperm and egg cells) fuse during fertilization, the resulting zygote will have the correct number of chromosomes.
Double cell division process that leaves the four newly formed cells with half the chromosomes of the original cell?
Meiosis is the double cell division process that results in four haploid cells, each with half the number of chromosomes as the original diploid cell. Meiosis involves two rounds of division (meiosis I and meiosis II), which reduce the chromosome number from diploid to haploid. This process is important for sexual reproduction in eukaryotic organisms.
Why must sperm and egg cells reduce chromosomes before fusing?
Reducing chromosomes before fusing, through meiosis, ensures that the resulting offspring will have the correct number of chromosomes. If there is no reduction, the resulting zygote would have double the number of chromosomes, leading to genetic abnormalities and potential developmental issues in the offspring.
Why is meiosis necessary after fertilization to maintain chromosome number?
Meiosis is necessary after fertilization in order to reduce the chromosome number by half, ensuring that the resulting offspring will have the correct number of chromosomes. This reduction is essential for maintaining genetic diversity and preventing the accumulation of too many chromosomes over generations. Additionally, meiosis helps to mix genetic material from two different parents through the process of recombination, leading to variation among offspring.
How was it possible to predict that meiosis occurred before there was direct visual evidence for it?
It was possible to predict meiosis before direct visual evidence because the behavior of chromosomes during cell division was observed, and scientists noticed that the number of chromosomes in the daughter cells was half that of the parent cell. This observation led to the hypothesis that a special division process, later called meiosis, must be occurring to reduce the chromosome number.
Meiosis reduce the number of chromosomes by?
Meiosis reduces the number of chromosomes by half. This is essential for sexual reproduction, as it ensures that when gametes (sperm and egg cells) fuse during fertilization, the resulting zygote will have the correct number of chromosomes.
The net result of meiosis is to reduce the number of chromosomes in gametes to only one from each?

When and why does meiosis occur?
Meiosis occurs in sexually-reproducing organisms during the formation of gametes (sperm and egg cells). It is necessary to reduce the chromosome number by half, ensuring that when the gametes combine during fertilization, the resulting offspring will have the correct number of chromosomes.
Does meiosis reduce chromosome numbers?
Yes - the daughter cells produced in meiosis (gametes) have half the number of chromosomes as those in the original cell. This is why meiosis is referred to as 'reduction division'. However, as meiosis produces cells which are involved in sexual reproduction - the chromosome number in the species remains constant. This is because when the two gametes combine, the resulting organism has the correct number of chromosomes (half from each gamete).
In what type of cell division does the chromosome number reduce by one half and gametes form?
Meiosis produces gametes which have half the number of chromosomes that other cells of the body have.
In an ovum the number of chromosomes could best be described as?
In an ovum, the number of chromosomes is haploid, meaning it contains half the number of chromosomes found in other cells of the body. This is because during the process of meiosis, the ovum undergoes division to reduce the number of chromosomes by half in preparation for fertilization.
Double cell division process that leaves the four newly formed cells with half the chromosomes of the original cell?
Meiosis is the double cell division process that results in four haploid cells, each with half the number of chromosomes as the original diploid cell. Meiosis involves two rounds of division (meiosis I and meiosis II), which reduce the chromosome number from diploid to haploid. This process is important for sexual reproduction in eukaryotic organisms.
How many chromosomes will egg cell of the weed have?
The egg cell of a weed will typically have half the number of chromosomes as a normal body cell of that weed species. This is because the egg cell undergoes meiosis to reduce the chromosome number in preparation for fertilization.
State the purpose of meiosis?
the purpose of meiosis is to reduce the number of chromosomes in new cells to half the number of the original cell which is known as reduction division. The process also creates gamete cells which are also haploid cells because they contain half the DNA of the original cell.In simple terms the purpose of meiosis is to create genetically unique sex cells ( sperm and egg ) with half the normal number of chromosomes
Why must sperm and egg cells reduce chromosomes before fusing?
Reducing chromosomes before fusing, through meiosis, ensures that the resulting offspring will have the correct number of chromosomes. If there is no reduction, the resulting zygote would have double the number of chromosomes, leading to genetic abnormalities and potential developmental issues in the offspring.
Why is meiosis necessary after fertilization to maintain chromosome number?
Meiosis is necessary after fertilization in order to reduce the chromosome number by half, ensuring that the resulting offspring will have the correct number of chromosomes. This reduction is essential for maintaining genetic diversity and preventing the accumulation of too many chromosomes over generations. Additionally, meiosis helps to mix genetic material from two different parents through the process of recombination, leading to variation among offspring.
Why is it necessary to have two separate divisions in meiosis?
Having two separate divisions in meiosis is necessary to reduce the chromosome number by half, ensuring that the resulting gametes have the correct number of chromosomes. This reduction is essential for sexual reproduction, as the fusion of two gametes during fertilization will restore the full chromosome number in the offspring.
