I understand "instant sin". But what is "distant sin"? Do you mean the sins committed by our forefathers? There is a saying "mAtA pitA pAvam makkaL taliyilE". Is that what you are referring to?

I have been working on a hypothesis as to how the sins committed by someone would affect his posterity. The sins normally go with the souls. How do they know to tag on to the bodies of the posterity of the sinner? Karma might attach itself to the soul (according to Hindu and Bhuddist beliefs) and then on to the bodies occupied by that soul. But affecting posterity is a stretch even on the karma theory.

There is a burgeoning field called Epigenetics which explains certain diseases caused by silencing certain genes. But that should happen to the same person in his current birth. For example, if you commit a sin it might make changes around some of your genes and cause some disease down the road. Then if you reproduce the modification might affect your offspring too. But if your grandfather or father committed a sin after ​you were born then this does not apply to you.
