My friend Angie Bush is a most creative genetic genealogist whose daughter Brynne is apparently following in her footsteps. They do a lovely presentation on autosomal DNA together which includes this slide showing four generations of DNA inheritance, made with my ancestor chromosome mapper.
Little did I know when Angie asked me for a feature to select the colors herself what a clever thing she had in mind. Each grandparent is shown in two colors, one for each of their parents. Those same colors are carried through on each chart so the names next to the colors on Brynne’s chart are those of her eight great-grandparents. How wonderful to have four generations of family tested.
Here is the close-up of the ancestor chromosome mapper chart for just Brynne:
Interesting that she has chromosome 21 intact from her paternal great-grandmother Marilyn. Also notice how little recombination occurred on her X chromosome.
This presentation called “Ancestors in DNA” was given near me at the Carlsbad DNA Special Interest Group (DIG) and has been submitted for a number of upcoming conferences. Check back here to learn when they will be giving it. I really look forward to going to this one!
