The Claim
The frequency of the lactase persistence allele in Czech Roma populations is 27%, which is similar to the frequency observed in Indian populations, indicating a shared genetic origin consistent with a South Asian ancestry for the Roma people.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People of Czech Roma descent have the same frequency of a specific genetic variant related to digesting milk as people from India, which suggests their ancestors came from South Asia.
See the scientific wording
The lactase persistence allele frequency in Czech Roma (27%) closely matches that of Indian populations, supporting the hypothesis that the Roma people originated from South Asia and retained this genetic signature despite migration into Europe.
A genetic change near the lactase gene keeps the enzyme that digests milk active after infancy, allowing adults to break down lactose in dairy products.
What the research says
1 studyThe study found that 27% of Czech Roma can digest milk as adults, just like many people in India — and this is very different from most Europeans. This suggests Roma people likely came from India long ago and kept this genetic trait.
