What makes a dominant trait?

The simplest situation of dominant and recessive alleles is if one allele makes a broken protein. When this happens, the working protein is usually dominant. The broken protein doesn't do anything, so the working protein wins out. If both copies of your MC1R gene code for broken proteins, then you'll have red hair.

What is the meaning of dominant traits?
