Natural clines and human management impact the genetic structure of Algerian honey bee populations
CONCLUSIONS: The differences between the two main genetic clusters suggest differential breeding management between eastern and western Algeria, with greater exchange of genetic material over long distances in the east. The lack of detected admixture events suggests that, unlike what is seen in many places worldwide, imports of queens from foreign countries do not seem to have occurred on a large scale in Algeria, a finding that is relevant for conservation purposes. In addition, the proposed panel of 96 markers was found effective to distinguish Algerian from European honey bees. Therefore, we conclude that applying this ...

Mapping restricted introgression across the genomes of admixed indigenous African cattle breeds
CONCLUSIONS: To our knowledge, this is the first time genomic cline analysis has been applied to identify restricted introgression in the genomes of indigenous African cattle and the results provide extended insights into mechanisms (e.g. genomic incompatibilities) contributing to hybrid differentiation. These results have important implications for our understanding of genetic incompatibilities and reproductive isolation and provide important insights into the impact of cross-breeding cattle with the aim of producing offspring that are both hardy and productive.PMID:38097935 | PMC:PMC10722721 | DOI:10.1186/s12711-023-0086...

Genotype-by-environment interactions for feed efficiency traits in Nellore cattle based on bi-trait reaction norm models
CONCLUSIONS: Our results show evidence of G × E interactions on feed efficiency traits in Nellore cattle, especially in feeding trials with an average daily gain (ADG) that is far from the expected of 1 kg/day, thus increasing reranking of animals.PMID:38097941 | PMC:PMC10722809 | DOI:10.1186/s12711-023-00867-2 (Source: Genet Sel Evol)

Managing genomic diversity in conservation programs of Chinese domestic chickens
CONCLUSIONS: Conservation programs of three Chinese domestic chicken breeds have maintained their genomic diversity to a sustainable degree. The small ex situ conserved populations, which are maintained in controlled environments, retain less genetic diversity than populations conserved in situ. In addition, the transfer of populations from their place of origin to another site for conservation purposes results in genetic differentiation, which may be caused by genetic drift or adaptation. This study provides a basis for further optimization of in situ and ex situ conservation programs for domestic chicken breeds in China....
