On that sheet line 67, you see a Dixit Brahman
Bihar, India (Z94/L342+ L657+ Y9+ Y7- Y2351+ Y2353+ Y2392+)
Line 209 Jatt Muslim Pansota, Toba Tek Singh, possibly Hoshiarpur (Z94+ L657+Y9+ Y7+) (Bhatti maternal)
These two have a common ancestor Y9, even when one is a Brahmin and the other one is a Jatt, children of the same father Y9, after that one is Y7- and the other one is Y7+, cousins now. This Jatt is related to this Brahmin around R-Y9V4070/Y9 formed 3600 ybp, TMRCA 3600 ybp, see

Line 418 Shah Gujarati (Z94/L342+ L657+ Y9+ Y7+)
Line 444
Malayali R1a1a1b2a1a* (R-Y7)
Now see this Shah and
Malayali are even more closely related to
Line 209 Jatt Muslim Pansota, Toba Tek Singh, possibly Hoshiarpur (Z94+ L657+Y9+ Y7+) (Bhatti maternal) than the above Brahmin.
As all 3 are Y7+, and this means that this Y7 person, is the father of these 3 people now belonging to three different communities, all are the sons of just this one Y7 father. And this is how we can sort out the relationship of the individuals and groups or communities.
Also see
http://www.yfull.com/tree/R-Y7/, R-Y7V4155/Y7 formed 3600 ybp, TMRCA 3100 ybp.
But these R1a>>Y7 Jatts are related to other J2 Jatts only about 45000 ybp, and to L-M357 Jatts about 44000 ybp.
One thing to keep in mind is, that all Jatts are not the children of one ancestors but various tribes, that came to be known as Jatts later on sometime, and that time line can be determined like in the example above.
