Simultaneous Estimation of Null Alleles and Inbreeding Coefficients [PDF]

Journal of Heredity, 2008
Although microsatellites are a very efficient tool for many population genetics applications, they may occasionally produce "null" alleles, which, when present in high proportion, may affect estimates of key parameters such as inbreeding and relatedness coefficients or measures of genetic differentiation.

The effect of inbreeding on the growth ability of meat sheep breeds in the Czech Republic

Czech Journal of Animal Science, 2021
The aim of this study was to present the trend of inbreeding and to estimate the effect of inbreeding on the growth ability of lambs in the three most common sire breeds in the Czech Republic: Suffolk (SF; n = 49 345), Charollais (CH; n = 14 189) and ...

Technical Note: Recursive Algorithm for Inbreeding Coefficients Assuming Nonzero Inbreeding of Unknown Parents [PDF]

Journal of Dairy Science, 2008
A recursive algorithm to calculate inbreeding coefficients was modified to account for nonzero inbreeding of unknown parents. The modification was done by changing one part of a recursive formula in which the inbreeding of an animal with at least one unknown parent is not zero and replacing it by the mean inbreeding of all animals born the same year ...

Differences in cynomolgus macaque populations used for infectious disease research

Animal Models and Experimental Medicine, EarlyView.
Cynomolgus macaques, a species of Old World primate native to southeastern and eastern Asia and the island of Mauritius, are one of the most important nonhuman primate models for infectious disease. Research into the population genetics of cynomolgus macaques has found significant differences between macaques native to different areas, particularly ...

Removing exogenous information using pedigree data

, 2011
Management of certain populations requires the preservation of its pure genetic background. When, for different reasons, undesired alleles are introduced, the original genetic conformation must be recovered.

Relationships between estimated autozygosity and complex traits in the UK Biobank [PDF]

, 2018
Inbreeding increases the risk of certain Mendelian disorders in humans but may also reduce fitness through its effects on complex traits and diseases. Such inbreeding depression is thought to occur due to increased homozygosity at causal variants that ...

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

Evolution, 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.

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 ...

Genetic Diversity, Adaptation, Wild Introgression, and Coat Color Mutation of Golden Yak

Animal Research and One Health, EarlyView.
Genetic diversity, adaptation, wild introgression, and coat color mutation of golden yak from two populations on the Qinghai‐Xizang Plateau. ABSTRACT The golden yak lives on the Qinghai‐Xizang Plateau with a golden coat and adapts to high altitudes and strong ultraviolet environment. The golden coat is a prominent phenotype in many domesticated species,

Pedigree analysis of Santa Inês sheep and inbreeding effects on performance traits

Revista Mexicana de Ciencias Pecuarias, 2020
Population parameters such as effective population size and coefficients of inbreeding are important information of a population but have rarely been studied in Santa Inês sheep.
