Sex cells (gametes) are formed in the gonads. In males, sperm cells are produced in the testes. In females, egg cells come from the ovaries. All the egg cells a female will ever release are produced before birth, but they mature annually.
Sex cells (sperm and egg) differ from body cells in that they do not have a full set of chromosomes. Sex cells are haploid, meaning they only have one set of chromosomes, while body cells are diploid, with two sets of chromosomes. This difference allows sex cells to combine during fertilization to create a genetically diverse offspring.
Sex cells have half the number of chromosomes as body cells, so if the body cells have 12 chromosomes, the sex cells will have 6 chromosomes. This reduction occurs through the process of meiosis, where the chromosome number is halved to ensure proper genetic information is passed on during sexual reproduction.
Human cells have 46 chromosomes (call that 2n, or 2 times n). Now then, if an egg cell + sperm cell = fertilized egg (which becomes a human), how many chromosomes do each have? An egg cell must have 23 chromosomes, and a sperm cell must have 23 chromosomes, because 23 + 23 = 46. When the egg (23) and sperm (23) combine to form a fertilized egg, this egg will now have 46 chromosomes. So human sex cells have n, or 23 chromosomes. If you mean to distinguish somatic chromosomes from sex chromosomes, then you have 22 pairs of somatic chromosomes plus one pair of sex chromosomes, for a total of 46 chromosomes.
Body cells typically have a diploid number of chromosomes, meaning they have two sets of chromosomes. Sex cells, or gametes, have a haploid number of chromosomes, meaning they have one set of chromosomes. This allows for the correct number of chromosomes to be restored upon fertilization.
Meiosis forms sex cells, also known as gametes, such as sperm and egg cells.
male sex cells are formed in anther and female sex cells in the ovary
In humans, all the somatic cells (body cells) are diploid. However, gametes (sex cells) such as sperm and egg cells are haploid. Gametes have half the amount of genetic material than which is found in somatic cells. These are the only human cells which are not diploid.
Body cells. Meiosis deals with sex cells
Cause body cells have twice the chromosomes a sex cell has Body cells have 46 chromosomes and sex cells have 23 chromosomes.
Meiosis is the process by which sex cells are formed.
by fertilization
Either sex cells or body cells. Sex cells perform mieosis, and body cels perform mitosis.
Body cells or somatic cells have a full number of chromosomes while sex cells have one half the number.

Sex cells are haploid, meaning they only have one set of chromosomes, while body cells are diploid, with two sets of chromosomes.

No, somatic (non-sex) cells have twice the number of chromosomes that sex cells have.
