Each "human body cell" has 46 chromosomes. But human sex cells have 23 unpaired chromosomes in each cell.
Chromosomes are thread-like molecules that carry hereditary information for everything from height to eye color.
Model Center Model organisms share with humans many key biochemical and physiological functions that have been conserved maintained by evolution. In fact, the sex chromosomes are quite interesting, not just because of what they cause or what their role is, but also because they're so different from the other chromosomes that we have in the complete human genome.
