Getting Closer to Identifying My DNA Cousins on Chromosome 21

Getting Closer to Identifying My DNA Cousins on Chromosome 21

I’ve been fortunate to make a 3rd cousin connection on my Jones/Kelly line who I share quite a bit of DNA with. This cousin helps me divide my DNA matches into my maternal maternal column. Even still, it’s been difficult making sense of how I relate to my other matches. I have a small group that match me on a sequence on chromosome 21 and I’m getting a little closer to figuring out how we are related. A Cluster of…

Three Cousins, Three Different Amounts of DNA Shared

Three Cousins, Three Different Amounts of DNA Shared

I  have three cousins who have had their DNA tested. Three cousins who match me (thank goodness). Three completely different amounts of DNA passed down. How is that possible? Recombination. My three cousins and I have all taken autosomal DNA tests. As I understand it, although everyone who descends from a specific ancestor carries that person’s DNA, not everyone carries it on the same chromosomes or carries the same amount on the same chromosomes. That is called  recombination. With each…
