Area of Science:

Genomics
Animal Genetics
Evolutionary Biology

Background:

Indigenous animal populations develop unique adaptations to local environmental stressors like heat, drought, and disease.
Natural and artificial selection drive the acquisition of favorable traits, leaving genomic signatures in populations.
Understanding these adaptations is crucial for livestock resilience and evolution.

Purpose of the Study:

To characterize genomic diversity in indigenous chickens from equatorial Africa.
To identify genomic regions under selection that may confer adaptive advantages.
To understand the genetic basis of adaptation in African chicken ecotypes.

Main Methods:

Genotyping of indigenous chickens from Uganda and Rwanda, and Kuroiler chickens using a 600k Chicken Genotyping Array.
Analysis of genomic diversity and identification of selection signatures.
Gene ontology enrichment analysis of identified genomic regions.

Main Results:

Admixture was detected among Ugandan, Rwandan, and Kuroiler chicken populations.
Genes in regions of homozygosity are associated with lipid metabolism, immune function, and stress responses.
Signatures of selection are enriched for genes involved in health and oxidative stress processes, including antioxidant, apoptosis, and inflammation functions.

Conclusions:

Indigenous African chickens possess alleles under environmental selective pressure, facilitating adaptation to harsh conditions.
Enriched gene ontology terms related to stress responses suggest common adaptive mechanisms or admixture effects.
Genomic insights can inform strategies for improving chicken resilience in challenging environments.
