My comments: It is true that Hindu & Catholic Goans came from similar backgrounds but over the last 500 years there have been offspring from unions of the Portuguese and Goans. The percentages of such liaisons were probably greater among upper caste Catholic Goans leading to differences not only between castes but also on lines of religion. I am grateful to Santosh for answering my queries. This prompted me to look at other sources and readers may be interested in the following review article: The Indian Genome Variation database (IGVdb): a project overview [Website: www.igib.res.in] Brahmachari, SK and others.
