When i decrease their standard values within Gedmatch so you’re able to a hundred snps/step 1 cm I started to get an idea as to why they had eg strange common rates. Across the almost all their chromosomes, the outcomes was indeed similar to the figures below:

Considering the ongoing argument off just how lower you could come in setting default values when comparing kits, this product are a helpful illustration that those very small segment fits come in everybody’s DNA, besides their suits.

DNA review to own use at home was launched in the early 2000’s and also grown widely common nowadays, though some principles and you will confidentiality concerns was basically voiced.
