Record 2 2009-04-28

English

Subject field(s)
  • Genetics
CONT

Conservation genetics is a mixture of ecology, molecular biology, population genetics, mathematical modeling and evolutionary systematics (the construction of family relationships). It is both a basic and an applied science. Scientists must first understand the genetic relationships of the organisms under study. ... management techniques must then be applied by wildlife managers to preserve biological diversity in these species. ... Information about the genetic diversity of the [plants and] animals under study helps scientists and managers in forming strategies to preserve and protect the diversity of plants and animals worldwide.

CONT

Conservation genetics [is] concerned with the population genetics principles involved in the maintenance of feral species. The maintenance of the populations depends on inbreeding, outbreeding, effective population size, deleterious mutation, reproductive success, adaptation to captivity, reintroduction, vagility, outbreeding depression, extinction, etc.

French

Domaine(s)
  • Génétique
CONT

[...] un but important de la génétique de la conservation est l'identification des gènes ou des régions de génome responsables des traits phénotypiques qui peuvent augmenter l'adaptation locale ou les traits qui peuvent faciliter l'adaptation au futur changement climatique. Cette connaissance peut alors être utilisée pour concevoir des stratégies de conservation donnant priorité à la conservation des populations qui ont une fréquence élevée de ces gènes ou d'une combinaison de ces gènes.

Record 3 1999-11-09

English

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

In a four-way hybrid, F1s are used as both seed and pollen parents, because inbreeding depression has a negative effect on pollen production, too.

French

Domaine(s)
  • Génétique
  • Cultures (Agriculture)
DEF

Hybride résultant de croisement de deux hybrides doubles.

Record 4 1992-03-19

English

Subject field(s)
  • Plant Biology
CONT

outbreeders... have various morphogenetic mechanisms that favour crossing, tend to carry deleterious recessives in the heterozygous state and show inbreeding depression.

French

Domaine(s)
  • Biologie végétale
CONT

les allofécondées [...] possèdent divers mécanismes morphogénétiques favorisant la pollination croisée, tendent à transporter des gènes récessifs délétères à l'état hétérozygote et montrent une dépression due à la consanguinité.
