This subclade can be considered a Zagrosian Neolithic Farmer branch of haplogroup J2. The origin of this haplogroup among Khorasani Persians is mostly related to Bronze Age Pre-Aryan Central Asian-related populations such as BMAC and IGW, which were most likely carried by Avestan-related groups into Iran.
