In humans, each cell nucleus contains 23 pairs of chromosomes a total of 46 chromosomes. The first 22 pairs are called autosomes which look exactly the same in both males and females. The 23rd pair of chromosomes is called an allosome. These sex chromosomes differ between males and females. Females have two copies of the X chromosome, while males have one X chromosome and one Y chromosome.

In classical Cartesian algebra, the x axis is defined as a horizontal number line defining the distance from a zero point called the origin. The y axis is a vertical line de â¦ fining the vertical distance from the same origin. This system has been adapted to define axes on any number of graphing systems, from Microsoft Excel to modern machine tools.
