| blood relative | 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) |

| relative aperture | <microscopy> The ratio of the focal length of a lens to the diameter of its entrance pupil. This gives a number known as the f-number, usually written f:8, f:16, etc. Thus, if the focal length is divided by the number 8, 16, etc., the result will be the diameter of the entrance pupil of the lens, or if the diaphragm of the lens is wide open it will be very nearly the diameter of the free aperture of the lens. See: F-number. (05 Aug 1998) |
| relative basal area | An estimate of basal area for trees, such as produced by the Bitterlich sampling technique. (09 Oct 1997) |
