Some light hearted but imp info.
You find repetitive configurations, Yogas in family members, even community. could be termed as hereditary configurations in many cases. Let me term just few of what i come across.
1) Both children of a person hv exchange between 9 & 11 lords 1/3

2) Shani in 12th is repeated in father and son.
3) Rahu found in 6th in almost all members of a family.
4) Yogas like Shani-Moon and Mars-Venus. combination/mutual aspects passed from parents to children. 2/3

5) Few charts (6 nos) of Kashmiri Hindu Pandits i observed of late, i saw unmissable influence of Ketu on all of them. Most had birth Nakashtra of Ketu &/or strong connection to the 4th.
Why Ketu > Karaka of terrorist, it uprooted K Hindus from Valley. 3/3 https://twitter.com/PunyaPrakop_/status/1205529085419671552?s=20
