The effect of inbreeding rate on fitness, inbreeding depression and heterosis over a range of inbreeding coefficients [PDF]
Evolutionary Applications, 2014 AbstractUnderstanding the effects of inbreeding and genetic drift within populations and hybridization between genetically differentiated populations is important for many basic and applied questions in ecology and evolutionary biology. The magnitudes and even the directions of these effects can be influenced by various factors, especially by the ...

The use of frozen semen to minimize inbreeding in small populations
, 2002 In this study, we compared the average coancestry and inbreeding levels for two genetic conservation schemes in which frozen semen from a gene bank is used to reduce the inbreeding in a live population.

Evolution of precopulatory and post-copulatory strategies of inbreeding avoidance and associated polyandry [PDF]
, 2017 Inbreeding depression is widely hypothesised to drive adaptive evolution of pre-copulatory and post-copulatory mechanisms of inbreeding avoidance, which in turn are hypothesised to affect evolution of polyandry (i.e., female multiple mating).

Quantifying inbreeding avoidance through extra-pair reproduction [PDF]
, 2015 Extra-pair reproduction is widely hypothesized to allow females to avoid inbreeding with related socially paired males. Consequently, numerous field studies have tested the key predictions that extra-pair offspring are less inbred than females ...

, 2008 Inbreeding is common in plant populations and can affect plant fitness and resistance against herbivores. These effects are likely to depend on population history.

Opposition to Inbreeding Between Close Kin Reflects Inclusive Fitness Costs
Frontiers in Psychology, 2018 Due to the intense selection pressure against inbreeding, humans are expected to possess psychological adaptations that regulate mate choice and avoid inbreeding. From a gene’s-eye perspective, there is little difference in the evolutionary costs between

The effect of genomic information on optimal contribution selection in livestock breeding programs
, 2013 Long-term benefits in animal breeding programs require that increases in genetic merit be balanced with the need to maintain diversity (lost due to inbreeding). This can be achieved by using optimal contribution selection.

Inbreeding depression in livestock: comparing trait groups and inbreeding measures
, 2022 Inbreeding depression has been documented for many livestock populations. We compared inbreeding depression estimates (1) between trait groups, and (2) between different pedigree-based and genomic inbreeding measures.

Journal of Dairy Science: Homozygosity, which can arise from several genetic mechanisms including inbreeding, is frequently observed in the offspring of related parents. This inbreeding can lead to a reduced performance, owing to a phenomenon known as inbreeding depression ...

A multivariate analysis with direct additive and inbreeding depression load effects
Genetics Selection Evolution, 2019 Background Inbreeding is caused by mating between related individuals and its most common consequence is inbreeding depression. Several studies have detected heterogeneity in inbreeding depression among founder individuals, and recently a procedure for ...
