MyHeritage bought Promethease a few months ago. It is a site that provides reports from DNA data that you upload. MyHeritage bought them when MH decided to provide their own health reports.
Anyway, the regular Promethease reports were made to be free through 2019. They used to cost $10. If you have downloaded your autosomal DNA test data from any of the major sites, go to https://promethease.com and get your FREE reports.
IMPUTE: assign a value to something by inference from the value of the products or processes to which it contributes.
IMPUTATION in Genetics: using statistical inference to deduce unknown genotypes based on known ones. Genotype imputation is usually performed on SNPs, the most common kind of genetic variation.
IMPUTATION is the process whereby your DNA is tested and then the results “expanded” by inferring results for additional locations, meaning locations that haven’t been tested, by using information from results you do have. In other words, the DNA is adjacent locations is predicted, or imputed, by their association with their traveling companions. In DNA, traveling companions are often known to travel together, but not always. From DNAeXplained.
How does this relate to me? Some DNA testing companies allow you to upload your DNA DATA file generated at another company. For example, Family Tree DNA will accept DATA files from 23andMe as input to their Family Finder product. The price for this service is lower than if you took the “spit test” obviously because they do not have to mail kits and do the processing required to sequence the DNA.
But, there is a “gotcha” here. The different companies do not all use the same chips nor sample the same SNP locations. They also upgrade their own chips periodically. To be able to be backward compatible and to provide MATCHING services, they need to “equalize” the data enough so they will be reasonably accurate. This is fine except when chromosome browsers are used to compare segments.
My view is to remember your purpose. If you are after accuracy above all else, then spend the extra money to get the “spit test”. But if you just want to broaden your cousin match pool, by all means try uploading your data somewhere else at the discounted pricing.
An example of how we used data uploads. Sisters A & B had tested at FTDNA. Sister C had tested at 23andMe. In order to get all 3 sisters together, we downloaded sister C data from 23andMe and then uploaded it into FTDNA for only $19.
AncestryDNA and 23andMe do NOT accept DNA data uploads, the other companies do. I recommend testing at one of these companies, downloading the data and uploading elsewhere. Unless, like me, you want purity everywhere. 🙂
Let’s discuss it.

Join in the fun and merriment while we get to know others who are also interested in learning about their family histories. There will be lots of fun and good cheer, and the food is great! 🙂
Doors open at 5:30 pm, the party starts at 6:00pm in the Fireside Room. Enter through the FHC doors.
We’ll see you at the Family History Center, 1024 Noche Buena, Seaside, CA., left rear of building. For Information: (831) 915-9465.

This is a time to give thanks for a wonderful year.
The local Daughters of the American Revolution chapter is holding its 39th annual Ancestor Roundup Genealogical Seminar again in January.
Many of you know this is the best genealogical meeting on the central California coast! As always, it will be held in the Church of Jesus Christ of Latter-Day Saints here in Seaside, CA. If you are working on your genealogy, you really need to come to this seminar. I know I’ll be there.
The seminar will be held all day Saturday, January 25, 2020 from 8:00 am to 3:30 pm. Lunch is provided.
There will be over 35 classes during the day. You can pick and choose from the calendar and actually attend up to 5 classes during the day, including the Keynote. The keynote speaker will be Karina Robinson! Karina currently serves as special assistant to the State Librarian at the California State Library. Also, for the DNA junkies in the audience, Katherine Borges from ISOGG, and Pamela Brigham from Silicon Valley Computer Genealogy Group will both be back.
There are 2 ticket options, both include lunch! $25 gives you a downloadable syllabus, $35 gives you a printed syllabus. Get the signup form by clicking below. Print the signup form to mail in.
Go ahead — download and print the above form and mail it in. You know you’re going to do it anyway!

At the last meeting of the DNA Sig, we took a poll. This was a not statistically significant poll, but it was written and in person. The poll just surveyed what Genealogy & DNA company people actually were using. The list was limited to the items on the poll. There are other DNA companies out there, but they were not on the list.
This group,had Ancestry tree highest, but AncestryDNA and FTDNA were equal! We will repeat this little survey again.
