∙ 13y agoit is halved so that when the sperm joins with the egg (which is also halved) it will produce one cell with the regular amount of chromosomes, instead of twice as many as it should. this is also how a baby gets traits from both its mom and dad, because half of its full set of chromosomes comes from mom, the other half from dad.

∙ 7y agoBecause the chromosomes in the sperm and the egg have to join together (during fertilization of the egg) to form a new cell which will grow to form a new organism.
If they did not have half the number of chromosomes, each time this happened you would double the number of chromosomes in the new cell formed by fertilization.

All cells within an organism will have the same number of chromosomes except the gamete?
All cells within an organism will have the same number of chromosomes, which is the diploid number. The gametes, on the other hand, will have the haploid number of chromosomes.
How many chromosomes in bone marrow?
Every cell has the same number of chromosomes (except for sex cells), based on the specific organism's species. Humans have 46 chromosomes in each nucleus, and their sex cells have 23.
The only haploid cells found in humans are?
Reproductive cells or sex cells of an organism contain haploid number of chromosomes. All other body cells (or somatic cells) contain diploid number of chromosomes
How does the number of chromosomes in gametes of an organism that reproduces sexually differ from the numbers of chromosomes in other cells?
Unlike somatic (body) cells, gametes have two time the number of chromosomes as body cells. Gametes (2n). Body cells (n). For example, human 46 chromosomes in gamete cells but half of that (23) in body cells.
How do the numbers of chromosomes in cells compare with the number of chromosomes in sex cells?
The mother gives the egg and the father gives the the sperm and wine they come to get it can make a zygote in other words the baby

How are sex cells different from other cell in the body?
Sex cells have 1/2 the number of chromosomes of a normal cell (23)

Unlike somatic (body) cells, gametes have two time the number of chromosomes as body cells. Gametes (2n). Body cells (n). For example, human 46 chromosomes in gamete cells but half of that (23) in body cells.
Do chimpanzees body cells have 24 chromosomes?
Yes, all great apes have 24 chromosomes while humans have 23.
Why is it neccessry to reduce the chromosome number of gametes but not other cells of an organism?
Gametes are sperm and egg cells. When the sperm fertilizes the egg, their genetic material is joined to form a new cell called a zygote. Because both the sperm and egg cells have half the number of chromosomes as in normal body cells, the zygote will have the full number of chromosomes as in normal body cells.

How does sex cells differ from ordinary cells?
Sex cells, called gametes, are different to other cells in that they contain half the number of chromosomes. So in a human sex cell, there are 23 chromosomes, whereas a normal human cell has 46 chromosomes.
What occurs during meiosis?
During Meiosis the chromosomes pairs separate and are distributed to two different cells. The resulting sex cells have only half as many chromosomes as the other cells in the organism......
Gametes contain one half one quarter or is equal to the number of alles found in other cells in the body of an organism?
Gametes contain half of the number of chromosomes as somatic cells (the other cells of your body). These chromosomes have the same number of alleles on them as somatic cells, but gametes contain one allele of each gene while somatic cells contain two alleles of each gene. So, they contain half the amount of alleles that the rest of your cells do.
