To make predictions about coat color, or almost any other trait, in cria from specific breedings you need to understand some basic rules of genetics. Coat color is determined by genetics. When people say something is genetically determined, what they are really talking about is DNA. DNA is what codes for all of the proteins (things like hemoglobin, albumin, melanin, insulin, keratin tissues, hormones all the stuff that make up an alpaca), and for the instructions on how, when and where to make these proteins within the alpaca. Segments of DNA that code for proteins are called genes.
