Maybe because of the location of gene

[Darby]

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?
