Homozygosity and risk of childhood death due to invasive bacterial disease. [PDF]

, 2009
BACKGROUND: Genetic heterozygosity is increasingly being shown to be a key predictor of fitness in natural populations, both through inbreeding depression, inbred individuals having low heterozygosity, and also through chance linkage between a marker and

Behavioral inbreeding avoidance in wild African elephants

, 2007
The costs of inbreeding depression, as well as the opportunity costs of inbreeding avoidance,determine whether and which mechanisms of inbreeding avoidance evolve. In African elephants,sex-biased dispersal does not lead to the complete separation of male

Incestuous sisters: mate preference for brothers over unrelated males in Drosophila melanogaster.

PLoS ONE, 2012
The literature is full of examples of inbreeding avoidance, while recent mathematical models predict that inbreeding tolerance or even inbreeding preference should be expected under several realistic conditions like e.g. polygyny.

Correlation Analysis among the Various Inbreeding Coefficients of Pannon Ka Rabbits

Diversity
In a closed population with a limited population size, mating of related animals is unavoidable. In this study, the genealogy data of a synthetic maternal rabbit breed called Pannon Ka were used to calculate different inbreeding coefficients.

Inbreeding

Biotechnology in Animal Husbandry, 2007
The objective of this paper is to present to scientific and professional public the most common forms of inbreeding appearing or carried out with different kinds of domestic animals aimed to enhancement of the population production capabilities. In this way, by following the change of certain productive, reproductive and other characteristics, the kind

Inbreeding depression in Holstein cattle in Brazil

Revista Brasileira de Zootecnia
The objective of this study was to evaluate inbreeding depression in Holstein cows in Brazil, considering their 305-day milk production (MP), age of first calving (AFC), and calving interval (CI).

Release from natural enemies mitigates inbreeding depression in native and invasive Silene latifolia populations

Ecology and Evolution, 2019
Inbreeding and enemy infestation are common in plants and can synergistically reduce their performance. This inbreeding ×environment (I × E) interaction may be of particular importance for the success of plant invasions if introduced populations ...

Inbreeding depression in the Lizard canary breed estimated by pedigree analysis

Czech Journal of Animal Science, 2016
The influence of inbreeding depression on phenotypic traits of the Lizard canary from an Italian breeder was evaluated. The following traits were studied: birds' life span, number of surviving offspring, and morphological traits (type of plumage ...

Analysis of Levels of Inbreeding and Inbreeding Depression in Jersey Cattle

Journal of Dairy Science, 1992
A pedigree file of 157,015 male and female Jersey cattle (born after 1955) from the Canadian herdbooks was investigated for the occurrence of inbreeding. A large proportion of Jersey bulls and cows were inbred (32.4 and 36.3% for bulls and cows, respectively). However, average inbreeding coefficients of these inbred cows and of all cows were low. First

Selection, maternal effects and inbreeding in reindeer husbandry [PDF]

, 2003
In extensive grazing systems where several owners’ flocks are allowed to mix, selection strategies will also interact, due to gene flow between flocks. The aim of the thesis was to analyse breeding schemes in terms of genetic gain and rate of inbreeding (
