Estimation of inbreeding effect on conception in Czech Holstein

Czech Journal of Animal Science, 2019
The influence of calculated inbreeding coefficients on the conception of heifers and cows was analysed by a two-trait binary model for conceived/not conceived after each insemination on 677 234 Czech Holstein cows and heifers with 3 248 299 insemination ...

Revisiting Genetic Relationships of the Endangered Austrian Turopolje With Balkan and Commercial Pig Breeds Using Genome-Wide SNP Data. [PDF]

Anim Genet
ABSTRACT The endangered Austrian Turopolje (AT) pig population, which originated from six Croatian Turopolje founders imported during the early 1990s, is nowadays preserved through a national conservation project. This study aims to identify genetic relations, genetic distances and migration events between the AT population, four Austrian commercial ...

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.

Homozygosity and risk of childhood death due to invasive bacterial disease. [PDF]

, 2009
BACKGROUND: Genetic heterozygosity is increasingly being shown to be a key predictor of fitness in natural populations, both through inbreeding depression, inbred individuals having low heterozygosity, and also through chance linkage between a marker and

Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

Advanced Science, EarlyView.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

EXACT INBREEDING COEFFICIENTS IN POPULATIONS WITH OVERLAPPING GENERATIONS [PDF]

Genetics, 1978
ABSTRACT A theory is given that allows inbreeding coefficients to be calculated exactly for populations with overlapping generations. Emphasis is placed on providing equations well suited for computer iteration. Both monoecious and dioecious populations are considered and family size is not restricted to being Poisson.

Quantifying inbreeding avoidance through extra-pair reproduction [PDF]

, 2015
Extra-pair reproduction is widely hypothesized to allow females to avoid inbreeding with related socially paired males. Consequently, numerous field studies have tested the key predictions that extra-pair offspring are less inbred than females ...

Female‐Specific Risk of TAS2R Variants in Chronic Rhinosinusitis: A Hospital‐Based Cohort Study From the Taiwan Precision Medicine Initiative

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Bitter taste receptors (T2Rs) function in the innate immune defense of the sinonasal mucosa; however, the genetic association between the TAS2R gene family and chronic rhinosinusitis (CRS) remains understudied in Asian populations.
