Genetic diversity analysis of major Sri Lankan goat populations using microsatellite and mitochondrial DNA D-loop variations

The present study aimed at the genetic characterization of five major goat populations of Sri Lanka including four indigenous populations (Jaffna Local – JFL, Kottukachchiya – KOT, Southern – SLS and North Central – SNC) and one stabilized crossbred (German Boer x indigenous goats, also known as “Sri Lankan Boer” – SLB). Genetic diversity was evaluated using 15 microsatellite markers and the mitochondrial DNA D-loop variation. Allelic diversity and observed and expected heterozygosities were moderate, but less than Eurasian and Indian goat breeds. The overall mean estimated inbreeding coefficient (FIS) was 0.069 and significant heterozygote deficiency was detected in JFL (P
