Medical Definition of Blood relative
1. A relative of a person sharing some of the sources from which genes are derived. These will include many of the genes that operate in the blood and its constituents but no special importance attaches to the blood as a vehicle of inheritance. Spouses are not ordinarily blood relatives and when they are, the marriage is consanguineous and carries a higher risk than average of progeny homozygous by descent from ancestors in common. Such marriages are discouraged and within certain degrees of kindred may be illegal. Origin: a folk metaphor of breeding (05 Mar 2000)
