During metaphase 1, the chromosomes line up in the middle of the cell. The way the chromosomes line up is, , or independent. This independent alignment results in different possible arrangements or, ,assortments of chromosomes during metaphase. This in turn results in different, ,of chromosomes in cells. During sexual reproduction, the traits that are determined by the genes on these chromosomes are passed on from parents to offspring.

When homologous chromosome pairs align on the spindle during metaphase I the orientation of one pair is independent of the orientation of any other pair. This is known as independent assortment. Humans have 46 chromosomes, arranged as 23 pairs.
