In organisms where meiosis occurs to create gametes, sex cells are made to have half as many chromosomes as regular body cells have. For example, a human man's sex cell or gamete would have 23 chromosomes and the non-sex cells in his body (the ones that aren't produced in his testes) would contain 46 chromosomes. This is for the purpose of creating progeny that have an increased variety of genetic information. This is possible because the male gamete combines with the female gamete to create a whole new organism with a new combination of genetic information that has the correct number of chromosomes.
There are 23 Chromosomes present in a human cell.

23 pair of chromosones
Each gamete contains 23 chromosomes.

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

Mostly likely 50. Most organisms are diploid (2n), gametes are haploid (1n). If there are 25 chromosomes in the gamete, 25x2 = 50.

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.

For a species with three pair of chromosomes how many gametic combinations are possible?
In human gametes, chromosomes are not paired. Instead, each gamete has one set of 23 chromosomes, and is said to be haploid.
the number of chromosomes present in the somatic cells of rafflesia flower is 12... but as in gametes,gametes are formed by meiosis or reductional division ( in which the number of chromosomes becomes half the parent cell so that after fertilization, the original chromosome count is restored and the organism is identical), the number of chromosomes found in the games of raffleisa will be 12/2 or 6 chromosomes.
