The sex cells, or gametes, (egg and sperm) don't contain pairs of chromosomes. They each contain 23 singular chromosomes. When the egg and sperm combine, the resulting cell will have 23 pairs of chromosomes.
You have single copy of chromosomes in sex cell. You have total 23 chromosomes in sex cell. When sex cells from male and female combine, you get the double copies of chromosomes in human cells. You have 23 such double copies of chromosomes in your body cells.
There is only one pair of sex chromosomes.
Number of pairs of chromosomes depend upon species and vary from species to species .
23 chromosomes
There are 23 pairs of chromosomes in each human somatic cell. 22 pairs are exactly the same in both males and females. In males there are XY sex chromosomes and in females these are XX.
Normal body cells, also called diploid cells, contain 46 chromosomes. These are matched up in 23 pairs, one pair being the gender chromosomes.
Homologous pairs.
Each human cell has 23 pairs of chromosomes or 46 chromosomes.
A cell with pairs of homologous chromosomes. (it has two copies of each chromosome)
Gametes only have one of each chromosome, whereas somatic cells have a pair.
Our chromosomes are found in the nucleus of each of our body cells. We have 46 of them, matched up into 23 pairs.
Matched Pairs involves participants being selected for one group only but part of each group are matched for some relevant factors eg) age, gender, height. Kiecolt Glaser did a matched pairs experiment in 1995.

The hydrogen bonding across to the nitrogen's lone pairs in each match is strong enough in a correctly matched pair to hold the DNA molecules together.
they are called complimentary muscles
Each time a cell divides it's 23 PAIRS of chromosomes are divided and then 23 go to each of 2 new cells. Then each new cell with 23 chromosomes then replicates it's chromosomes so it has 23 PAIRs. Just look at a diagram of cell "mitosis". After the first mitosis: 46 pairs and 2 cells, Second round: 4 cells containing 92 PAIRS of DNA total. 3RD ROUND: Eights cells each containing 23 PAIRS of chromosomes: 8 x 23= 184 total chromosomes.
Human? 23 pairs as mitosis means ' to double.'
