Consanguinity
Definition:
(n.) The relation of persons by blood, in distinction from affinity or relation by marriage; blood relationship; as, lineal consanguinity; collateral consanguinity.
Example Sentences:

(3) Parental consanguinity suggests that an autosomal recessive mutation is the likely aetiology.
(4) Any patient with a fairly symmetrical 'quiet' eye disease, especially if congenital, should be suspected of having an hereditary disease--presumably due to a recessive gene, even if the parents are not consanguineous, but possibly due to a mutation which could prove dominant; a search of the literature in such cases is useful.
