order
(Science: zoology) A taxonomic classification between class and family. (biology) taxonomic group containing one or more families.A more exact taxon than a class, the primates are an example of a taxon order.

Gene orders is the permutation of genome arrangement. So far a fair amount of work trying to describe whether gene orders evolve according to a molecular clock (molecular clock hypothesis) or in jumps (punctuated equilibrium).
A disorder characterized by recurrent thoughts or behaviors (i.e. excessive handwashing or repeated doubt about having locked a door) that are severe enough to be time-consuming or cause significant impairment in social functioning.
Dominant Genetic Disorder
In dominant genetic disorders, if one affected parent has a disease-causing gene that dominates its normal counterpart, each child in the family has a 50% chance of inheriting the disease-causing gene and the disorder.
