Inbreeding Depression and Purging for Meat Performance Traits in German Sheep Breeds

open access: yesAnimals, 2023
This study provides estimates on genetic parameters, inbreeding depression and purging for meat performance measures from 25 German sheep breeds. All German meat, merino sheep breeds and breeds of other breeding directions with a sufficient number of ...

Sensitive males: inbreeding depression in an endangered bird [PDF]

open access: yes, 2010
Attempts to conserve threatened species by establishing new populations via reintroduction are controversial. Theory predicts that genetic bottlenecks result in increased mating between relatives and inbreeding depression.

Postcopulatory mechanisms of inbreeding avoidance in the island endemic hihi (Notiomystis cincta) [PDF]

open access: yes, 2011
Avoiding genetic incompatibility resulting from inbreeding is thought to be one of the main drivers of mate choice, promiscuity, and sexual conflict. Inbreeding avoidance has been found across a wide range of taxa and is predicted to be adaptive when the

Pedigree error due to extra-pair reproduction substantially biases estimates of inbreeding depression [PDF]

open access: yes, 2013
Understanding the evolutionary dynamics of inbreeding and inbreeding depression requires unbiased estimation of inbreeding depression across diverse mating systems.

On the close relationship between speciation, inbreeding and recessive mutations. [PDF]

open access: yes, 2010
Whilst the principle of adaptive evolution is unanimously recognised as being caused by the process of natural selection favouring the survival and/or reproduction of individuals having acquired new advantageous traits, a consensus has proven much harder

An effective rotational mating scheme for inbreeding reduction in captive populations illustrated by the rare sheep breed [PDF]

open access: yes, 2008
Within breeds and other captive populations, the risk of high inbreeding rates and loss of diversity can be high within (small) herds or subpopulations.

The existence of species rests on a metastable equilibrium between inbreeding and outbreeding [PDF]

open access: yes, 2011
Background: Speciation corresponds to the progressive establishment of reproductive barriers between groups of individuals derived from an ancestral stock.

Prediction of genetic gain from quadratic optimisation with constrained rates of inbreeding [PDF]

open access: yes, 2006
There are selection methods available that allow the optimisation of genetic contributions of selection candidates for maximising the rate of genetic gain while restricting the rate of inbreeding. These methods imply selection on quadratic indices as the

Inbreeding and selection on sex ratio in the bark beetle Xylosandrus germanus [PDF]

open access: yes, 2011
Background: Local Mate Competition (LMC) theory predicts a female should produce a more female-biased sex ratio if her sons compete with each other for mates.
