Genetic studies on Filipinos
Various genetic studies on Filipinos have been performed, to analyze the population genetics of the various ethnic groups in the Philippines.

The most frequently occurring
In particular, the type of O2-M122 that is found frequently among Filipinos in general, O-P164(xM134), is also found frequently in other Austronesian populations, including Polynesians.[12][13][14] Trejaut et al. 2014 found O2a2b-P164(xO2a2b1-M134) in 26/146 = 17.8% of a pool of samples of Filipinos (4/8 = 50% Mindanao, 7/31 = 22.6% Visayas, 10/55 = 18.2% South Luzon, 1/6 = 17% North Luzon, 2/22 = 9.1% unknown Philippines, 2/24 = 8.3% Ivatan).
The distributions of other subclades of O2-M122 in the Philippines were sporadic, but it may be noted that O2a1b-JST002611 was observed in 6/24 = 25% of a sample of Ivatan and 1/31 = 3.2% of a sample from the Visayas, O2a2a1a2-M7 was observed in 1/6 = 17% of a sample from North Luzon, 1/55 = 1.8% of a sample from South Luzon, and 1/31 = 3.2% of a sample from the Visayas, and O2a2b1a1a-M133 was observed in 2/31 = 6.5% of a sample from the Visayas.[13] A total of 45/146 = 30.8% of the sampled Filipinos were found to belong to Haplogroup O2-M122.[13]
In a study by Delfin et al. (2011), 21.1% (8/38) of a sample of highlanders of northern Luzon (17
)Haplogroups R-M343 and I-M253
After the 16th century, the colonial period saw the influx of genetic influence from other populations. This is evidenced by the presence of a small percentage of the Y-DNA
The analysis of the full
Haplogroup Q-M242
One study found that the Y-DNA of two out of 64 sampled Filipino males belonged to Haplogroup Q-M242 (which has its highest frequency among Native Americans and Asian Siberians and is also found in other Asians).[19]
Mitochondrial DNA haplogroups

From India
The Indian Mitochondrial DNA haplogroups, M52'58 and M52a are also present in the Philippines suggesting that there was Indian migration to the archipelago starting from the 5th Century AD.[20]
The integration of Southeast Asia into Indian Ocean trading networks around 2,000 years ago also shows some impact, with South Asian genetic signals that are present in the

Within that large group, with the exception of Ashkenazi Jews, we see little evidence of distinct clusters. This is consistent with considerable exogamy within this group. By comparison, we do see structure in the East Asian population, correlated with nationality, reflecting continuing endogamy for these nationalities and also recent immigration. On the other hand, we did observe a substantial number of individuals who are admixed between East Asian and European ancestry, reflecting ~10% of all those reporting East Asian race/ethnicity. The majority of these reflected individuals with one East Asian and one European parent or one East Asian and three European grandparents. In addition, we noted that for self-reported Filipinos, a substantial proportion have modest levels of European genetic ancestry reflecting older admixture."

Indian influence and possibly haplogroups M52'58 and M52a were brought to the Philippines as early as the fifth century AD. However, Indian influence through these trade empires were indirect and mainly commercial; moreover, other Southeast Asian groups served as filters that diluted and/or enriched any Indian influence that reached the Philippines
