All triats consist of a genotype and a phenotype. A genotype is the code previously mentioned that is passed on while a phenotype is the physical or actual result of the genes, such as hair color or eye color. Sometimes people breed things for specific traits. Monohybrid is done to breed one specific trait. Dihybrid is the breeding for two traits.
With all the genetic information being read in our bodies, it can be difficult to decipher all of the information. For that reason, epigenomes are in place. Epigenomes serve as puncuation marks for our genes and they help the proteins to do their job more efficently and accurately.
