Genome-wide assessment and mapping of inbreeding depression identifies candidate genes associated with semen traits in Holstein bulls

open access: yesBMC Genomics, 2023
Background The reduction in phenotypic performance of a population due to mating between close relatives is called inbreeding depression. The genetic background of inbreeding depression for semen traits is poorly understood.

Genomic patterns of homozygosity and inbreeding depression in Murciano-Granadina goats

open access: yesJournal of Animal Science and Biotechnology, 2022
Background Inbreeding depression can adversely affect traits related to fitness, reproduction and productive performance. Although current research suggests that inbreeding levels are generally low in most goat breeds, the impact of inbreeding depression

SELECTION AND INBREEDING DEPRESSION: EFFECTS OF INBREEDING RATE AND INBREEDING ENVIRONMENT [PDF]

open access: yesEvolution, 2006
The magnitude of inbreeding depression in small populations may depend on the effectiveness with which natural selection purges deleterious recessive alleles from populations during inbreeding. The effectiveness of this purging process, however, may be influenced by the rate of inbreeding and the environment in which inbreeding occurs.

Exploring the relationship between tychoparthenogenesis and inbreeding depression in the Desert Locust, Schistocerca gregaria [PDF]

open access: yes, 2017
Tychoparthenogenesis, a form of asexual reproduction in which a small proportion of unfertilized eggs can hatch spontaneously, could be an intermediate evolutionary link in the transition from sexual to parthenogenetic reproduction.

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]

open access: yes, 2016
PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

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

The environmental dependence of inbreeding depression in a wild bird population. [PDF]

open access: yesPLoS ONE, 2007
Inbreeding depression occurs when the offspring produced as a result of matings between relatives show reduced fitness, and is generally understood as a consequence of the elevated expression of deleterious recessive alleles.

Inbreeding depression is high in a self-incompatible perennial herb population but absent in a self-compatible population showing mixed mating. [PDF]

open access: yes, 2017
High inbreeding depression is thought to be one of the major factors preventing evolutionary transitions in hermaphroditic plants from self-incompatibility (SI) and outcrossing toward self-compatibility (SC) and selfing. However, when selfing does evolve,

A comparison of inbreeding depression in tropical and widespread Drosophila species. [PDF]

open access: yesPLoS ONE, 2013
The evolutionary history of widespread and specialized species is likely to cause a different genetic architecture of key ecological traits in the two species groups. This may affect how these two groups respond to inbreeding.

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).
