Genetic Diversity and Trends of Ancestral and New Inbreeding in Deutsch Drahthaar Assessed by Pedigree Data [PDF]
Animals, 2022 Loss of genetic diversity and high inbreeding rates confer an increased risk of congenital anomalies and diseases and thus impacting dog breeding. In this study, we analyzed recent and ancestral inbreeding as well as other measures of genetic variability

Coenzyme Q10 supplementation enhances HSP70 gene expression and preserves mitochondrial function in cryopreserved Peranakan Ettawa goat spermatozoa [PDF]
Veterinary WorldBackground and Aim: Inbreeding is a major concern in livestock breeding because it can reduce genetic diversity, impair fitness, and compromise long-term population sustainability.

Genetic Diversity and Trends of Ancestral and New Inbreeding in German Sheep Breeds by Pedigree Data [PDF]
Animals, 2023 In Germany, many autochthonous sheep breeds have developed, adapted to mountain, heath, moorland, or other marginal sites, but breeds imported from other countries have also contributed to the domestic breeds, particularly improving wool and meat quality.

Analysis of Ancestral Inbreeding Across Main Founders and Ancestors in the Polish Simmental Cattle Population [PDF]
AnimalsThis study estimated the impact of main founders and ancestors on inbreeding subdivision in the Polish Simmental cattle population. Two reference populations were defined: subset A (20,827 cows born 1984–2009) and subset B (19,554 cows born 2010–2020 ...

Genome‐Wide Homozygosity Predicts Inbreeding Depression in the Hihi/Stitchbird (Notiomystis cincta) Better Than Realised Load [PDF]
Evolutionary ApplicationsPopulation declines result in increasingly small populations, which often experience an increase in inbreeding. Inbreeding may be negatively associated with fitness traits like survival and reproduction, that is, inbreeding depression, and is therefore ...

Characterizing and Eliminating the Inbreeding Load
Veterinary Sciences, 2023 The authors evaluated the relevant literature related to purging, which is the interaction between selection and inbreeding in which the population may eliminate its inbreeding load at least partially. According to the relevant literature, the inbreeding

Predicting the rate of inbreeding in populations undergoing four-path selection on genomically enhanced breeding values [PDF]
Animal Bioscience, 2022 Objective A formula is needed that is practical for current livestock breeding methods and that predicts the approximate rate of inbreeding (ΔF) in populations where selection is performed according to four-path programs (sires to breed sons, sires to ...

Revised Calculation of Kalinowski’s Ancestral and New Inbreeding Coefficients
Diversity, 2020 To test for the presence of purging in populations, the classical pedigree-based inbreeding coefficient (F) can be decomposed into Kalinowski’s ancestral (FANC) and new (FNEW) inbreeding coefficients.

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 ...

Does haplodiploidy purge inbreeding depression in rotifer populations? [PDF]
PLoS ONE, 2009 BACKGROUND:Inbreeding depression is an important evolutionary factor, particularly when new habitats are colonized by few individuals. Then, inbreeding depression by drift could favour the establishment of later immigrants because their hybrid offspring ...
