How many people have only dominant traits
Answers
Answer:
Just because a trait is dominant does not mean it is common. Each color represents different levels of light eyes. Blue=80%+, teal=50-79%, olive=20-49%, brown=1-19%, black=none. Image courtesy of Dark Tichondrias
One of the first things we’re taught in genetics is that some traits are dominant and others are recessive. And that the dominant traits trump the recessive ones.
So brown eyes trump blue eyes. And red hair is always trumped by other hair colors. And so on.
From this, people often jump to the conclusion that the dominant trait is also the most common one. This isn’t always the case and there is no reason it should be.
Whether or not a trait is common has to do with how many copies of that gene version (or allele) are in the population. It has little or nothing to do with whether the trait is dominant or recessive.
