Genes are pieces of DNA that contain information for the synthesis of [[RNA|ribonucleic acids]] (RNAs) or [[Peptide|polypeptides]]. Genes are inherited as units, with two parents dividing out copies of their genes to their offspring. Humans have two copies of each of their genes, but each [[Egg cell|egg]] or [[sperm]] cell only gets ''one'' of those copies for each gene. An egg and sperm join to form a [[zygote]] with a complete set of genes. The resulting offspring has the same number of genes as their parents, butwith forone any gene, onecopy of theireach two copiesgene comescoming from their father and one from their mother.<ref name=Utah/>
