How are dominant and recessive alleles alike and different ?

Explanation:

Their genes determine the traits plus characteristics. Genes determine their eye shade, hair shade, and skin tone. Unlike the other alleles, they are withdrawn and are also much less possible to be expressed in many different ways. A dominant allele is also forced to be paired up with another recessive allele. Which also means that the most dominant and strongest allele is going to determine the characteristics by one hundred percent to one hundred percent.
