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).
Brown eye color used to be considered dominant, but scientists have now revealed that eye color is actually a multi-gene trait, rather than a single gene one. Itâs a little bit more complicated than to simply say that the brown eye color is the dominant one. Itâs more of a gene combination. Itâs also genetically possible to have your eye color divided into two colors on your iris, or different color irises.
