INBREEDING COEFFICIENT [4 records]

Record 1 2012-09-24

English

Subject field(s)
  • Genetics
  • Plant and Crop Production
CONT

The inbreeding coefficient will depart from 0 in several circumstances, namely :(1) if the population is small so that there is a likelihood of mating between relatives;(2) if there is assortative mating between like phenotypes;(3) if there is any tendency to assortative mating between relatives(e. g sib-crossing or, at the extreme, self-pollination). All three are relevant to plant breeding.

  • Génétique
  • Cultures (Agriculture)
CONT

Le coefficient d'autofécondation s'éloignera de 0 dans plusieurs circonstances: 1) la population est si petite qu'il existe une probabilité de croisements entre parents; 2) il existe des croisements préférentiels entre des phénotypes semblables; 3) il existe des préférences d'appariement entre certains parents (p. ex. croisements entre frères ou, à la limite, l'autofécondation). Ces trois cas s'appliquent à l'amélioration des plantes.

English

Subject field(s)
  • Animal Breeding
  • Biotechnology
CONT

The inbreeding coefficient(F) is the probability that two alleles at any locus are identical and descended from a common ancestor.

CONT

Since the inbreeding coefficient is a probability, it can assume only the values within the range of zero to 1. 0. Inbreeding coefficients express the amount of inbreeding that has accumulated starting from a specific point in the ancestry of the population....

Probabilité pour que deux gènes reçus par un individu en un même locus soient la réplique d'un même gène ayant appartenu à l'un des ancêtres communs au père et à la mère.

Record 3 1992-01-27

English

Subject field(s)
  • Genetics
CONT

Inbreeding is measured by F, the inbreeding coefficient, which is defined as the probability of identity of alleles by descent.

French

Domaine(s)
  • Génétique
CONT

L'autofécondation est mesurée par le coefficient d'autofécondation (F) que l'on défini comme étant la probabilité selon laquelle des allèles soient identiques par descendance.
