At my recent GEDmatch talk for i4GG, I warned the crowd that soon Genesis would be the only place at GEDmatch where you could upload new DNA kits. Well that day has actually come! Although your kits will migrate from GEDmatch, you may want to upload to Genesis if you cannot wait to see the comparisons. By the way, your GEDmatch login will work just fine at Genesis. Note that Genesis has the GEDmatch logo with an apple core next to it.
So why do you have to move to GENESIS? The problem is that some companies are using newer chips which test for different not completely overlapping markers: LivingDNA and 23andMe since August 2017. Why you may ask? Because the new chips test more SNPs and have more non-European ethnic coverage.
So how do you compare apples to oranges? Well Genesis seems to do a good job of it and the new one-to-many warns you when there are not enough SNPs in common for confidence in the results by highlighting in red. Have a look:
Notice that the last three columns are new. One shows how many SNPs overlap between the kits (in other words, how many SNPs are in common between the two sets of test results so can be compared), the next shows the date compared, and finally the company where the test was done is listed. The latter is needed because kits uploaded directly to GENESIS get assigned kit ids that start with a pair of random letters so the origin is not known from that. Note that migrated kits keep the A,T,M, and H single letters. Also many recently migrated kits will show an overlap of 0 because that has not yet been compared for them.
You may also notice that many columns are missing like haplogroups, gedcoms, and X matching; nor are the columns sortable. Hopefully these features will be added back soon. The display is more compact with the confusing clickable L replaced by clicking on a kit number to see its list of one to many matches. By the way the Tier 1 version of the one-to-many looks exactly the same as the one on GEDmatch.
The new home page is more compact and intuitive. I particularly like the new easy editing capability for your kits and that the icons used are explained above them. Just click that little pencil next to a kit to get to a form where you can change the kit from public to research, change your alias, add your haplogroups, etc. It is a good idea if you have uploaded multiple kits for the same person to mark all but one as research, so only the one appears in other people’s one-to-many results.

The one-to-one comparison needs to accommodate the different kit sizes and builds so the form looks slightly different. Click here for my slide with a screenshot of the new form. However my favorite new feature there is the ability to see just the fully matching regions (FIRs) which also gives the total cMs. This is only useful when comparing doubly related people like full siblings.
The DNA kit analysis tool shows you how many SNPs will actually be used in the comparisons and how many are slimmed. Missing is the number of no calls.
The rest of the list of DNA Applications includes most of the tools we depend on but is missing the frills like eye color and archaic kits. Gone is the click point for the multi kit analysis (MKA) which is only on the tier 1 menu. However you can always get to the MKA from one to many or the people who match 2 kits. [UPDATE 20-Mar-2019: you have to be a paid member to use MKA.] Plus the new MKA selection form is great! There are dropdowns to add in your kits and blanks to add other kits: Click here for my slide on that.
There are many new options in the multi kit analysis, including my pretty and compact chromosome browser which I previously blogged about.
Exciting new features are the ability to triangulate and do matching segment searches on just the kits you have selected in the multi-kit analysis. Sadly though, one of my favorite features, Tag groups, is not yet supported. Also all the GEDcom features are only on the old GEDmatch site at this point [UPDATE 20-Mar-2019: The gedcom features are on GENESIS now. Click here for my old post for more about them]
