I'm responding to a request by one of my Twitter/X followers who asked if I could do a quick review on genetic endogamy.

I'm related to my paternal GF 7 different ways, and it didn't even require an adoption.

#mixing through #migration => good
#endogamy (e.g. #caste etc.) => bad
This is the way! #mandalorian #evolution
Example from the #india subcontinent. But applies everywhere else, too.

One of our student RAs, Humreet, was working here with us this past winter on #religious #endogamy trends in #India. Here are some numbers she pulled from the 2019-20 @pewresearch.org's India #Survey Dataset:
Working on personal family DNA matches today.
Regular readers will know about my 'friendly farming families' of South East Kent causing significant endogamy.
In my personal offline tree now trying to easily identify the DNA match connections.

I'm eternally grateful my mother married out. My mother was from rural Georgia, and my father was from New Jersey. My maternal grandparents were 3rd cousins. I'm related to my grandfather 7 different ways.

My family tree is full of ancestors from the same 5 mile radius so why am I surprised that my Mum and Dad were remote cousins? Or that my ex-husband's tree intersects with mine at least twice on his maternal line? #DNA #endogamy #Genealogy /1
What aspect of #genealogy makes you the craziest, but in a good way. For me I think it's #endogamy. And not #DNA but when you are working the paper trails and you find that oh this person married some close relationship (blood or not)
Sunday afternoon #Jewish #familyhistory #genealogy #endogamy discovery - when you finally get around to deciphering a handwritten 1882 German marriage certificate because the groom is your relative and discover his bride is also your cousin and is already in your family tree!
Of interest to those with #endogamy, #pedigreecollapse, #cousinmarriages.
And there we have evidence of rural Southern #Endogamy. My maternal GF + my maternal GM = more matchesthan my mother.

When I first started doing #genealogy I thought the #endogamy I was finding within the #Jewish community in #Amsterdam was entertaining. Now I am focusing on a single surname in Kolomyya and I am tempted to just start working on the whole town (my direct ancestors were from nearby Stanislwow)
It's another #movie recommendation. Here's a quote that's stuck ...
"A #caste system needs scaffolding in order to maintain its hierarchies ... caste is an artificial chopping up of the population into fixed units. Each unit is prevented from fusing into another through a custom called #endogamy."
This is my favorite tool for visualizing pedigree collapse, @melrootsnwrites.bsky.social! #genealogy #pedigreeCollapse #endogamy
Because a lot of my ancestors come from the same 10 mile area I did the same without much success Now I am much more selective as to who to research and it is working #endogamy I also realised the other day that one of my more puzzling matches is through a remarriage and stepchildren
