Genetics aeons ago – II

Geneticists and medical researchers have recently discovered that marriages amongst close relatives could cause congenital disorders in the progeny.
The insight and the genius of our Rishis is such that they have laid out a system of ‘gotra’ (lineage) and have decreed long long ago that marriages amongst people of same ‘gotra’ is strictly prohibited, thereby preventing many congenital disorders due to marriages amongst close relatives!
We see that today’s science only attempts to corroborate those facts from our rich tradition, which the ‘modern man’ dismisses as superstition.
