In this function, y is the dependent variable and x is the independent variable. Variable used in an experiment or modelling can be divided into three types:  dependent variable ,  independent variable , or other.
About 70% of men have an eye dominance that matches their handedness. BUT, 30% do not. Most right handers have a dominant right eye and the bulk of southpaws a dominant left. These are the people who are well advised to shoot both eyes open (assuming that they are shooting from their strong shoulder).
There are also many things that your eye color reveals about you. Long ago, brown eye color was considered to be the dominant one. However, now scientists know that your eye color is a multi-gene trait, not a single-gene trait. So, itâs a little more complicated than to simply say that brown eye color is dominant. Itâs more of a gene combination. It is even genetically possible to have your eye color divided into two colors on your iris, or two different color irises.
