The inbreeding coefficients of the Hadza

open access: yesAnnals of Human Biology, 1977
A systematic tabulation is provided of the frequency of different types of inbreeding in the Hadza. Genealogical information was obtained for 931 individuals, alive and dead. Inbreeding was encountered with 165 individuals. There were 49 different types of inbred genealogy.

Inbreeding depression in red deer calves

open access: yesBMC Evolutionary Biology, 2011
Background Understanding the fitness consequences of inbreeding is of major importance for evolutionary and conservation biology. However, there are few studies using pedigree-based estimates of inbreeding or investigating the influence of environment ...

Pedigree analysis and inbreeding effects over morphological traits in Campolina horse population

open access: yesAnimal, 2018
Genetic improvement, without control of inbreeding, can go to loss of genetic variability, reducing the potential for genetic gains in the domestic populations.

Inbreeding in Holstein Friesian Cattle Population in Turkey

open access: yesJournal of Agricultural Sciences, 2022
Inbreeding is generally associated with a reduction in production and profitability. Therefore, it is essential that it be monitored and kept under control.

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

open access: yesGenetics 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.

The effect of inbreeding rate on fitness, inbreeding depression and heterosis over a range of inbreeding coefficients [PDF]

open access: yesEvolutionary 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 ...

EFFECT OF INBREEDING ON MORTALITY OF CAPTIVE TIGER [PDF]

open access: yesExploratory Animal and Medical Research, 2017
A study was carried out on the captive tigers of Nandankanan zoo, Odisha, India, to conclude any deleterious effect of inbreeding on mortality. A pedigree path analysis of 342 tigers was done to estimate the inbreeding coefficient of each tiger from ...

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

Genetic inbreeding depression load for morphological traits and defects in the Pura Raza Española horse

open access: yesGenetics Selection Evolution, 2020
Background Inbreeding is caused by mating between related individuals and is associated with reduced fitness and performance (inbreeding depression). Several studies have detected heterogeneity in inbreeding depression among founder individuals. Recently,

Inferences About Inbreeding Depression Based on Changes of the Inbreeding Coefficient [PDF]

open access: yesEvolution, 1990
In a mixed-mating population, the fitness of selfed individuals, relative to outcrossed individuals, can be estimated from observed changes of the inbreeding coefficient F. In general, three measurements of F, or two measurements of F and one of the selfing rate, spanning two generations are needed.
