    It all has to do with recessive genes.

    You have two copies of each gene - one from your mother and one from your father (this combination is known as your genotype). The combination of those two genes will lead to a specific trait (or phenotype).

    Different versions of a gene (a.k.a. "alleles") can be either dominant or recessive. Dominant means basically what you think it might - that version of the gene kind of "takes over" and expresses itself more strongly.
