Charts for Genetics

Published on: 21 December 2011

The Charting Companion Descendant and Outline Descendant charts provide some interesting genetic options: Y-chromosome and Mitochondrial. Both are useful for tracking the inheritance of genetic traits, passed on from ancestor to descendant.

Here is a chart of all the members of a family. The males are colored blue, and the females pink:

All the descendants

The Y-chromosome option shows all the male descendants who inherit this chromosome which determines gender. The Y chromosome can be used to determine paternity.

Y-chromosome – male descendants

The Mitochondrial option shows the female descendants who pass on the mitochondrial DNA to their daughters, and the sons who inherit, but do not pass it on:

Mitochondrial – female descendants (transmit), male (carry)

Unlike the other chromosomes that can recombine, The Y-DNA and Mitochondrial both pass down unchanged except for mutations, which makes them valuable for research and genealogical identification.
