Every human carries two copies of each gene in his chromosomes = alleles. Each allele comes from one parent. Hereditary diseases that occur within families are the result of a [[mutation]] in a single gene and follow a predictable inheritance. In other words, the disease already occurred in the ancestors of this family, a phenomenon that can be observed in the family tree. Inheritance can take place in the following ways:
