The objective of this study was to determine mtDNA sequences of the 481 bp HV1 region from two Indonesian native goat breeds, Kacang and Marica, to confirm the phylogeographic distribution of caprine haplogroup B in Southeast Asia. Based on these sequences, 12 haplotypes were observed and categorized into the predominant haplogroup B and minority haplogroup A, indicating that Indonesian native goats present the highest frequency (0.950) of the haplogroup B in the world. These results strongly emphasize previous observations of the haplogroup B frequencies tending to increase southeastward in Southeast Asia. Additionally, this suggests that goats primary bred into Southeast Asia might predominantly carry haplogroup B. This could essentially contribute to the understanding of the origin, propagation route and/or introgression history of Southeast Asian goats.

印度尼西亚本土山羊 (Capra hircus) 揭示了世界上最高的线粒体 DNA 单倍群 B 遗传频率

本研究的目的是确定来自两个印度尼西亚本土山羊品种 K​​acang 和 Marica 的 481 bp HV1 区域的 mtDNA 序列,以确认山羊单倍群 B 在东南亚的系统地理分布。基于这些序列,观察到 12 个单倍型,并将其分为优势单倍群 B 和少数单倍群 A,表明印度尼西亚本地山羊在世界上呈现单倍群 B 的最高频率(0.950)。这些结果强烈强调了先前观察到的单倍群 B 频率在东南亚倾向于向东南方向增加。此外,这表明最初繁殖到东南亚的山羊可能主要携带单倍群 B。这可能有助于了解起源,
