Definition of Reproductive cells
Reproductive cells: The eggs and sperm are the reproductive cells. Each mature reproductive cell is haploid in that it has a single set of 23 chromosomes containing half the usual DNA amount.
Except for the eggs and sperm, each cell in the human body -- there are 100 trillion cells in each of us -- contains the entire human genome, all the genetic information necessary to build a human being, and this information is encoded within the cell nucleus in 6 billion base pairs, subunits of DNA, packaged in 23 pairs of chromosomes, one chromosome in each pair coming from each parent.
The reproductive cells -- the eggs and sperm -- are thus notable exceptions to the usual rules concerning chromosomes, genes, and DNA.Source: MedTerms™ Medical Dictionary
