| Wright's inbreeding coefficient | <genetics> The percentage of homozygous alleles an individual has. The probability that any two genes in an individual have the same ancestral origin (which is shared by both parents). (09 Oct 1997) |

| coefficient of inbreeding | A statistical way of gauging how close two people are as to the genes. The coefficient of inbreeding (symbolised as F) is the probability that a person with two identical genes received both genes from an identical ancestor. Take first cousins who by definition share a set of grandparents. So for any particular allele (gene) in the father, the chance that the mother inherited the same allele from the same source is 1/8. Further, for any gene the father passes to his child, the chance is 1/8 that the mother has the same gene and 1/2 that she transmits that gene to the child so 1/8 X 1/2 = 1/16. Thus, a first-cousin marriage has a coefficient of inbreeding F =1/16. The added risks to the offspring of first cousins depend not only upon this coefficient of inbreeding but also upon the genetic family history and, in some cases, upon test results (for example, for beta thalassaemia for first cousins of Italian descent). However, there are always added risks from the mating of closely related persons and those risks are not negligible. (12 Dec 1998) |

| Wright's syndrome | <syndrome> Pain running down the arm, numbness, paresthesias, and erythema, with weakness of the hands; due to abduction of the arm for a prolonged period (e.g., during sleep or necessitated by occupation) which stretches the axillary vessels and the nerves of the brachial plexus. Synonym: subcoracoid-pectoralis minor tendon syndrome, Wright's syndrome. (05 Mar 2000) |
| Wright's version | A cephalic version employed in cases of shoulder presentation when the shoulders are pushed upward while the breech is moved toward the centre of the uterus by the other hand; the head is then guided into the pelvis. (05 Mar 2000) |

| attenuation coefficient | 1. <radiobiology> Compton: The fractional number of photons removed from a beam of radiation per unit thickness of material through which it is passing as a result of Compton effect interactions. 2. Linear: The fractional number of photons removed from a beam of radiation per unit thickness of material through which it is passing due to all absorption and scattering processes. 3.
