to dominant or not to dominant that is the question

Genetics as it applies to evolution, molecular biology, and medical aspects.

Maybe because of the location of gene

Think of two versions of a single protein - from two alleles of a single gene type. The proteins don't do quite the same thing.

If the effect of one version can hide the effect of the second - the most obvious example is one that works and one that doesn't - you've got dominant / recessive. This doesn't kill the cell if the protein isn't doing something critically important (like eye color in humans - blue eyes is a non-functioning pigment allele, but it's not working won't hurt you). There can be times where both proteins work, but one is just much more powerful - light green eye pigments will be covered by very dark brown.

Does that help?
