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.
Range refers to the y-axis. Domain refers to the x-axis. Range refers to the y-axis. Domain refers to the x-axis.
The domain refers to the variable that is changing in an equation. I suppose that your domain would usually be graphed along the horizontal axis (commonly called the x-axis, even when there is no x variable). You could be working in the time domain where you graph something with respect to time (distance that someone ran for 30 seconds).
