Dominant vs. Recessive Phenotype

These brothers are an excellent example of dominant vs. recessive phenotypes because of they’re extent of varying traits. Both of the bot on the right’s parents as well as his brother have brown hair. The boy on the right, however, has red hair because his parents are both carriers of the red hair gene while their brown hair gene is dominant. So the boy on the right carries two red hair genes making it possible for him to be the only child with red hair. Both boys, however, have freckles because face freckles are a dominant trait.
