In brief: Genetic term
Genetic disorders fall roughly into dominant and recessive based on inheritance.
If only one parent has a gene (brown eyes) but all children have that trait, then it's dominant; recessive traits require that both parents have the gene (blue eyes). If each parent has only one gene with that trait, then 1/4 of the children will express the trait.
