Inbreeding depression in Solanum carolinense (Solanaceae), a species with a plastic self-incompatibility response [PDF]

, 2008
Background Solanum carolinense (horsenettle) is a highly successful weed with a gametophytic self-incompatibility (SI) system. Previous studies reveal that the strength of SI in S. carolinense is a plastic trait, associated with particular S-alleles. The

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

, 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]

, 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

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

, 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).

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

, 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.

The role of inbreeding in the extinction of a European royal dynasty. [PDF]

PLoS ONE, 2009
The kings of the Spanish Habsburg dynasty (1516-1700) frequently married close relatives in such a way that uncle-niece, first cousins and other consanguineous unions were prevalent in that dynasty.

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

, 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

Grid search approach to discriminate between old and recent inbreeding using phenotypic, pedigree and genomic information

BMC Genomics, 2021
Background Although inbreeding caused by the mating of animals related through a recent common ancestor is expected to have more harmful effects on phenotypes than ancient inbreeding (old inbreeding), estimating these effects requires a clear definition ...

The existence of species rests on a metastable equilibrium between inbreeding and outbreeding. An essay on the close relationship between speciation, inbreeding and recessive mutations

Biology Direct, 2011
Background Speciation corresponds to the progressive establishment of reproductive barriers between groups of individuals derived from an ancestral stock.

Inbreeding depression for kit survival at birth in a rabbit population under long-term selection

Genetics Selection Evolution, 2020
Background Accumulation of detrimental mutations in small populations leads to inbreeding depression of fitness traits and a higher frequency of genetic defects, thus increasing risk of extinction.
