Re: Ancestry's Drastic Changes Dash Hopes of Finding Connections #dna

Personally I do not find small segments of any use whatsoever, as they go so far back in time that they are unreliable, and give faulty results. It is the 20cm plus which are the key to finding recent ancestors. Unfortunately Ancestry only records total cm length and not individual chromosome cm length so their data has to be uploaded to Gedmatch or another supplier like  FTDNA, 23andme,MyHeritage to get this information. 

However, I agree 20cm could be seen as a high cut off - I would prefer say 15 cm, but this would need to go hand in hand with Ancestry giving its customers individual chromosome lengths like all the other suppliers.
