There is still a chance that it will not be passed down, but more than likely it will be. With that though, if the alleles that are being passed down are both dominant; than the alleles are both shown and that is called codominance (Barekzi, 2016). There are two other possibilities for dominant traits as well. Those are complete dominance and incomplete dominance. Complete dominance is when the offspring only looks like one of their parents and not like the other and incomplete dominance occurs when the offspring does not look like either one of its parents (Barekzi, 2016). Either one of these could have also contributed to the difference in appearance between the two brothers. One could have inherited all of their traits from the father or mother; while the other one could have inherited none of the traits. However, one of the parents could also
