On the expected relationship between inbreeding, fitness, and extinction

open access: yesGenetics Selection Evolution, 2006
We assessed the expected relationship between the level and the cost of inbreeding, measured either in terms of fitness, inbreeding depression or probability of extinction. First, we show that the assumption of frequent, slightly deleterious mutations do

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.

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

Comparing pedigree and genomic inbreeding coefficients, and inbreeding depression of reproductive traits in Japanese Black cattle

open access: yesBMC Genomics, 2023
Background Pedigree-based inbreeding coefficients have been generally included in statistical models for genetic evaluation of Japanese Black cattle. The use of genomic data is expected to provide precise assessment of inbreeding level and depression ...

Genetic diversity and inbreeding in the Greek Skyros horse [PDF]

open access: yes, 2008
Inbreeding and heterozygosity levels were calculated in a population of 77 horses of the endangered Skyros breed that had been raised since 1988 at an experimental farm. Twenty one horses were inbred with average inbreeding coefficient of 0.11 (+/-0.02).

ON THE MEASUREMENT OF INBREEDING DEPRESSION [PDF]

open access: yesEvolution, 1994
Theory has shown that the fitness consequences of inbreeding can play a major role in the evolution of sex and reproduction (Maynard Smith 1977; Lloyd 1979; Shields 1982; Kondrashov 1985; Lande and Schemske 1985; Holsinger 1988; Charlesworth et al. 1991; Uyenoyama and Waller 1991 a and references therein).

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.

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

Strategies for controlling rates of inbreeding in MOET nucleus schemes for beef cattle [PDF]

open access: yes, 1994
A closed MOET (multiple ovulation and embryo transfer) nucleus scheme, with overlapping generations, was modelled for beef cattle by stochastic simulation. Selection was carried out for 25 years on a trait measurable in both sexes and with a heritability
