Meiosis reduces chromosome number from diploid (2n) to haploid (n).
There must be one copy of either the paternal or maternal of EACH chromosome (one of the two homologous chromosomes) for each chromosome.
The ten total chromosomes are replicated into 10 pairs of sister chromatids, 5 homologous PAIRS of chromosomes.
After Meiosis I, the homologus PAIRS are separated into two daughter cells (Reducing 2n to n), but sister chromatids are still intact.
After Meiosis II, Sister chromatids of each of the two cells divide, forming 4 haploid cells, 5 chromosomes.

The number of chromosomes in a organism can vary. Humans have 46 chromosomes, or 23 pairs.
The do come in pairs.
For a species with three pair of chromosomes how many gametic combinations are possible?

36 i believe
Since a somatic cell (body cell) has 2n sets of chromosomes, and a gamete has n sets of chromosomes, then in this case: 18 = n, so 2n = 36. This organism has 36 chromosomes in its somatic cells.
Different organisms have different numbers of chromosomes. For example, humans have 23 pairs of chromosomes (46 total) while cows have 30 pairs (60 total) and goldfish have 50-52 pairs (100-104 total).
Hapliod cells have no pairs of chromosomes
Haploid cells have no pairs of chromosomes.
