People go through the details of ancestry to find out whether the proposed person belongs to same lineage. While choosing, people may pay attention to the skin complexion, hair, and other features. But fiinally when it comes to deciding, they do it blindly.
A research, published in BioMed Central's open access journal Genome Biology, shows that Mexicans mate according to proportions of Native American to European ancestry, while Puerto Ricans are more likely to settle down with someone carrying a similar mix of African and European genes.
Neil Risch, from the University of California, San Francisco, and his team of researchers studied the effects of ancestry on partner choice in Mexicans and Puerto Ricans.
Risch said, "Latin America provides a unique opportunity to study population structure and non-random mating, due to the historical confluence of European, Native American and African racial groups over the past five centuries. We found that assortative mating, that is partner choice based on a shared ancestry, is very common in these populations".
According to the study, our DNA influences our desires, which remains mysterious. The place of living or socio-economic status could not explain the ancestral influence on romance.
