DNA Testing/Character Resemblance *Note: the picture on the left has nothing to do with DNA testing, I just thought it was great! :-) So, you're doing your character sketch and wondering about the genetics of recessive eye coloring. You have two people with blue eyes, so what color would the babies be? Blue. Why? Blue is a recessive gene. In order to disrupt the blue gene, you need to sprinkle in a dominant color, i.e. brown. The scientific explanation is below: This is the simplest case of dominance. The allele that produced the working protein would be dominant over the allele that produced the defective protein. Individuals with two copies of the working allele and individuals with one copy of the working and one copy of the defective allele would both be able to produce working protein. Only individuals with two copies of the defective allele would be unable to produce working protein. The allele that produces this defective protein would be recessive to the allele that prod...
