Recombination is the process by which progeny derive a combination of genes different from that of either parent. During the process of meiosis or gamete cell production, each reproductive cell receives at random one representative of each pair of chromosomes, or 23 in all. Since there are two chromosomes in each pair, meiosis results in 223, or about 8.4 million, different possible combinations of chromosomes in human eggs or sperm cells. The union of egg and sperm cells therefore results in over 70 trillion (223 X 223) different possible combinations - each one representing half of the genetic material from the father and half from the mother. In this manner, human genetic material is effectively shuffled with each generation producing the diversity seen in the world today.
