Predominately TK y ht branches:
C-M130+: minor ones according to Cai et al., fig. S1; major hts are shared with HMs and STs
D1-M15+: no according to Cai et al., fig. S1, and Shi et al., fig. 3; instead, TK hts belong to ST and HM branches
O1-M119+: yes according to Cai et al., fig. S1; sometimes they share hts with Taiwanese aborigines, sometimes they share them with Austronesians other than the latter
O2a-M95+: minor ones according to Cai et al., fig. 2; they derive from predominately MK hts; some hts are shared with Austronesians outside of Taiwan, implying that MKs were assimilated by Austronesians, part of whom became TK
O2a-M95+, M88+: short ones according to Cai et al., fig. S1; one ST branch is longer; major hts are shared with HMs and MKs
O3-M7+: no according to Cai et al., fig. 2; probably mostly MKs and HMs assimilated by TKs
O3-M134+, M117-: minor ones according to Cai et al., fig. S1
O3-M134+, M117+: very short ones according to Cai et al., fig. 2; the most common ht is shared by people from different language families; i.e., it seems to imply that M117+ expanded more or less simultaneously within TK, ST, HM and MK populations; by contrast, derivatives are most common in STs
