Charts for Genetics

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.

Tell the story of your family genetically!

  2. Family trees are most important to future generations than the current as some families does not have record of all their family history. Family tree diagrams are the best way to illustrate genealogy structure of a family. You can create family tree charts using family tree maker . Find more family tree templates in the diagram community of Creately.
