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.

Average coefficient of inbreeding and percentage inbreeding depression on cognitive abilities.

, 2014
Almost all the factors shows the same trend of inbreeding depression viz. PIQ > FSIQ > VIQ, though there is a significant difference among the categories of each factor.Average coefficient of inbreeding and percentage inbreeding depression on cognitive ...

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

PLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Coefficients of relationship and inbreeding among Finnish Ayrshire and Holstein-Friesian

Agricultural and Food Science, 2008
Pedigree data from national breeding value evaluations were used in calculation of the coefficient and rate of inbreeding, average coefficient and rate of relationship and generation intervals for the Finnish Ayrshire and Holstein-Friesian dairy cattle ...

Evaluation of Inbreeding in the Slovak Simmental Breed and Its Effect on Length of Productive Life

Animals
This study aimed to estimate the average inbreeding coefficient in Slovak Simmental dairy cattle and evaluate the effect of inbreeding on the length of productive life. All pedigrees included 463,282 animals dating back to 1914.

Inbreeding coefficients and coalescence times

Genetics Research, 1991
SummaryThis paper describes the relationship between probabilities of identity by descent and the distribution of coalescence times. By using the relationship between coalescence times and identity probabilities, it is possible to extend existing results for inbreeding coefficients in regular systems of mating to find the distribution of coalescence ...

Facial attractiveness is only weakly linked to genome–wide heterozygosity

Frontiers in Psychology, 2023
IntroductionIt has been frequently suggested that overall genomic heterozygosity and, particularly, heterozygosity of loci on the so-called major histocompatibility complex (MHC), which is responsible for the recognition of foreign substances/ pathogens ...

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

PLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

Inbreeding Depression in Two Mimulus Taxa Measured by Multigenerational Changes in the Inbreeding Coefficient [PDF]

Evolution, 1993
In mixed-mating plant populations, one can estimate the relative fitness of selfed progeny w by measuring the inbreeding coefficient F and selfing rate s of adults of one generation, together with F of adults in the following generation (after selection).
