Purging of inbreeding depression within the Irish Holstein-Friesian population [PDF]
Genetics Selection Evolution, 2009 The objective of this study was to investigate whether inbreeding depression in milk production or fertility performance has been partially purged due to selection within the Irish Holstein-Friesian population.

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 ...

Ancestral inbreeding only minimally affects inbreeding depression in mammalian populations. [PDF]
Journal of Heredity, 1997 Inbreeding depression can be reduced, or purged, by selection against deleterious alleles. This prediction is the basis of the recommendation that captive wildlife populations suffering from inbreeding depression be intentionally bred from healthy inbred animals. Yet data on the effectiveness of purging inbreeding depression are few.

Genomic analysis of the inbreeding load for body weight, carcass and reproductive traits in the Rubia Gallega beef cattle population [PDF]
Genetics Selection EvolutionBackground Inbreeding, resulting from mating between relatives, leads to inbreeding depression, which can be traced back to hidden ancestral inbreeding loads.

Inbreeding depression due to recent and ancient inbreeding in Dutch Holstein–Friesian dairy cattle [PDF]
Genetics Selection Evolution, 2019 Background Inbreeding decreases animal performance (inbreeding depression), but not all inbreeding is expected to be equally harmful. Recent inbreeding is expected to be more harmful than ancient inbreeding, because selection decreases the frequency of ...

Correlation Analysis among the Various Inbreeding Coefficients of Pannon Ka Rabbits
DiversityIn a closed population with a limited population size, mating of related animals is unavoidable. In this study, the genealogy data of a synthetic maternal rabbit breed called Pannon Ka were used to calculate different inbreeding coefficients.

Pedigree-based analysis of genetic variability in the Chinese Crested dog population in Poland [PDF]
Animal Science and Genetics, 2023 The aim of the study was to analyse the level of genetic diversity within the small population of Chinese Crested dogs bred in Poland, considering the common occurrence of hereditary diseases, which is probably linked to the high level of inbreeding ...

Genetic Diversity and the Impact of the Breed Proportions of US Brown Swiss in German Brown Cattle
Animals, 2021 Increase of inbreeding and loss of genetic diversity have large impact on farm animal genetic resources. Therefore, the aims of the present study were to analyse measures of genetic diversity as well as recent and ancestral inbreeding using pedigree data

Balancing gain and diversity: Optimal contribution selection for sustainable genetic improvement in sugarcane. [PDF]
Plant GenomeAbstract Sugarcane (Saccharum spp. hybrids), the source of ∼80% of the worlds sugar, has experienced a plateau in genetic improvement over recent decades. This stagnation is largely due to the crop's complex polyploid genome and long breeding cycles, which limit the efficiency of traditional selection methods.

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
