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.
Gametes have half the number of chromosomes - therefore if the diploid number is 22, the gametes would have 11 chromosomes.
4. Two gametes get together to make something new. Just double up!

A gamete has half the diploid number of chromosomes, so in this case, the gamete would have 15 chromosomes.
This is not entirely accurate. All cells in an organism carry the same number of chromosomes, except for gametes (sperm and egg cells) which are haploid and carry half the number of chromosomes as normal body cells (diploid).
Gametes have half the number of chromosomes - therefore if the diploid number is 22, the gametes would have 11 chromosomes.
Humans have 23 pairs of chromosomes, with 22 pairs of autosomes and one pair of sex chromosomes. During gamete formation, the chromosome number is halved, resulting in gametes with 23 chromosomes. Therefore, the organism that has 20 chromosomes in one of its gametes would not be human.

Haploid numbers of chromosomes are typically found in the gametes (sperm and egg cells) of an organism. These cells contain half the usual number of chromosomes, which is important for maintaining the correct chromosome number in the offspring after fertilization.

They merge.
A gamete has half the diploid number of chromosomes, so in this case, the gamete would have 15 chromosomes.

This is not entirely accurate. All cells in an organism carry the same number of chromosomes, except for gametes (sperm and egg cells) which are haploid and carry half the number of chromosomes as normal body cells (diploid).
When a zygote is diploid it obtains two sets of chromosomes. Gametes contain one set of chromosomes. Therefore, 6 chromosomes would amount to 3 sets of gametes.
