Wow...finally the tool I've been looking for! Thank you for this!! I was adopted as a baby and have been struggling to figure out which parent is maternal and which is paternal and all of that crazy stuff, and this tool just answered that question for me! I have one close relation that can only be on my maternal side because of the amount of shared cMs and segments between us. You just single handedly blew my research brick wall wide open for me!!

Hello! Great video!! I was wondering if you could do a video on BigY DNA on FTDNA? My brother did the test and I am struggling to learn/ understand the results and how to utilize them. I have joined projects and they have grouped him with matches. So what exactly does that mean? I have hit a brick wall and I'm hoping this information can help me break through it. I know this is a long comment! I appreciate your videos! Very informative! Love the energy you both bring to the channel! It's appreciated!😊

My largest DNA match, with someone that I can't work out my connection to through paper trails, is 56cM & 2 seg. When I enter him in, it gives such a large variety of options, that it isn't entirely useful. I can see how it would be useful to those who have bigger questions about closer relatives. It would be great to be able to still go deeper than this. But we'll have to wait. If you could determine how strong your connection to your mother and father are (likewise strength to paternal and maternal grandparents, and great-grandparents), it would help narrow down the strength of the connection of these further cousins, if you knew you had a stronger or weaker connection on that side of the tree. I would like to see Ancestry do two things. 1. Give you the ability to select DNA segments in the Chromosome painter, to see who your DNA matches are on differing parts of your DNA. 2. Create an estimated tree of DNA matches, automatically grouping DNA matches according to not only how they match with you, but how they match with each other, and the strength of your DNA connection to that part of your tree. Having DNA matches I think would be more useful, if you could see two things, 1. Which DNA segment (specifically) is being shared, and 2. which end of the segment is being shared.

The issue with closer relatives is that it's far easier to work out who they are without using a tool like this. Looking at shared matches can mostly narrow down the possibilities along with some logical deduction. The bigger issue is when you have a match that doesn't fit and you have a branch with no close relatives. In my case my dad doesn't have any close relatives on his dads side and because we don't know who his dad was it's hard to link all this unknown matches

@d.t.r.8036 Год назад

Hey Andy, I'm only at where you are about to start the FTDNA data (so forgive me asking if you wind up covering this later on in the video) but I gotta ask this before my ADD kicks in and it slips my mind.... Is this going to be the least bit useful for DNA matches that might ultimately wind up being connected to us in multiple ways? I already know that SharedcM on DNA painter isn't designed to work in that situation (altho I think he's working on a version that hopefully might at some point). I'm thinking not only back to the video you did not too long ago answering a viewer question about those kinds of matches, but also to those I have encountered where I have matches that are descended from a marriage btwn gr-grandchildren of my MM3Ggrandparents and my MP3Ggrandparents.

@TrevorEMayo 5 месяцев назад

As of Jan 2024 looks like they have removed the Paternal/Maternal piece from the results. There must have been a problem.

@margaretford1011 Год назад

I wonder how they have factored out (or in) junk segments - like those silly 2cM bits that My Heritage includes. I think Ancestry discards them and Ftdna lets you filter them out, but were they included in the data that the author used to determine his tool findings?

@sandrajerue9579 Год назад

I really like watching your videos but, I just have a hard time really understanding how to figure everything... I am new to learning this and trying to research.

@glenjones6980 Год назад

Like most of us I would imagine you have several more distant matches that make no sense rather than dozens of close relatives' results (and dozens of trees to draw on as seems to be the case in most of the uploads.

@tinplategeektoo Год назад

I have recently done my first DNA test and do find that it can be challenging in how the matches relate. So you are not alone here. It just will take time and patience to figure things out. These tools offer a guide to help narrow your research options so have a use. Good luck with your research

@johnandrea2111 Год назад

I wonder why the largest segment isn't part of the prediction.

@heatherdrake9846 Год назад

I wonder if the shared cM beta probabilities are closer?

@glenjones6980 Год назад

I have two matches to unknown maternal relatives at 168cM and 199cM, lets say they are called 'A' and 'B'. They are full sisters confirmed by DNA at 2810cM (as far as I can tell there is no other relationship possible at that amount) . The daughter of B has also tested, this batch of tests is the only set from three closely related individuals I can compare to my own test. The most likely relationship for A is 41% probability in the 2C1R Group and 28% in the 2C group. The most likely relationship for B is 83% probability in the 2C Group and just 5% in the in the 2C1R Group. The daughter of B just confuses things further. If her mother is genuinely in the 2C group she should really fall into the 2C1R Group but it's only 5% likely , she (the daughter) is most likely to be in the 3C1R Group or 4C Group (both at 24%). I've tried plotting the results for A and B in WATO separately (over 40 possible scenarios) and combined (over 70 scenarios) and it suggests that A and B are most likely to be from different generations, pretty much the same scenario SegcM is suggesting as the most likely. Given that A and B share 2810cM the results once again make no sense and make it almost impossible to try and work out how we link. A and B do not link to anyone on my maternal grandmother's side so I suspect the link is on my maternal grandfather's side but the census and paper trail of certificates shows no link between them.

Have you reviewed the cMSolver Tools?

@FamilyHistoryFanatics Год назад

I haven't yet but it's on my very long list.

@sandramoore8903 Год назад

I am female and adopted. I thought I knew which side of the family was maternal and which was paternal until I tried that new tool against what I thought was a paternal side. It said they were a maternal side to me. Since I have 2 X chromosomes...How does it know which side? Thank you very much for any information you can give me.

@suzannemcclendon Год назад

Andy, I am probably having a pre-operative doodle brain here (David is the patient), but I have a question about MM1C, PM1C, etc. Are you meaning the person is the mother's first cousin on her mother's side and father's first cousin on his mother's side, etc.? If not, then, I'm very confused. I know what a maternal 1C is (the child of my mother's siblings) and a paternal 1C (child of my father's siblings), but not MM1C, etc. Please clarify. Thanks!

@pamjenkins5716 Год назад

If it's your maternal side but it's the 1st cousins paternal side, you have a MP1c from your perspective. And your PM1c from your 1st cousins's perspective. You and your 1st cousins parents were brother and sister.

About Centimorgans, Why does your Highest Personality, (from certain, Personality Category), comes from, Family Members, that you share, Low or Medium Centimorgans with? For example, My Number one type, of women, who I think are more Attractive, than any other type of women, in the Face and Personality, are Mediterranean women. (My number one) favorite type, (but not the only type, of women, I like). Some of my Mediterranean Family Members, It starts with 71 CM and others, all the way down to, 10 CM. 95%, of my Mediterranean Family Members, are coming from, My Mother's Father. Now, Besides Centimorgans, the Percentage, of my Mediterranean DNA, is less then 20%, because 95%, of it, come from one, Grandparent, or one Grandparent Grandparent. Its's funny but, why are my Favorite type of women, coming from, my low percentages?

@awizenwoman Год назад

Unfortunately, these tools are useless for me, as I've inherited about 30-50% of my paternal DNA from my greatx5, whose Scottish DNA was overwhelmed with Stewart endogamy, but hope it helps others. I have close relatives who do not share any DNA with me, though others do. I've traced my common DNA ancestors, even back to 24thGGF.

@munfordb Год назад

I agree endogamy really confuses things

@FamilyHistoryFanatics Год назад

Yep. This tool is problematic for endogamy or non-close relatives. Endogamy makes everything more challenging to be sure.

@BrandenEbert-ey9nb Год назад

I find this tool is garbage. It’s way easier to narrow down the possibilities from the bigger groups than being led astray on a higher percentage wrong possibility. When trying to decipher between paternal side aunt/uncle niece/nephew vs a half sibling it keeps giving higher percentages to grandparents and maternal for that matter. It’s a tool that is just going to lead the researchers astray. Most people that are needing and using tools like this are researching Half type relationships within 1st-2nd generation. I’ll stick to the SharedcM tool until someone can refine Half relationship research better.
