the Siam chicken bioresource project: genetic diversity and origin of Thai chicken breeds

Three separate studies have delved into the genetic characteristics, origins, and unique attributes of various chicken breeds in Thailand, providing crucial insights for future breeding programs.
The first study focused on Chee Fah and Fah Luang, black-boned chicken breeds in Chiang Rai, Thailand. Despite their economic and cultural significance, little was known about their genetics. Mitochondrial DNA D-loop sequencing and microsatellite genotyping revealed shared genetic heritage with Chinese black-boned chickens, suggesting their origin. Distinct genetic patterns were identified compared to Thai domestic chickens and red junglefowl, indicating crossbreeding and introgression during domestication. Interestingly, the Chee Fah and Fah Luang chickens from different localities exhibited different gene pool structures, possibly influenced by environmental factors like elevation.
The second study centered on the Mae Hong Son chicken, a local breed in Northern Thailand. Genetic analyses, inc...
