Tuesday Question 🧬

How alive is your DNA?

You being alive represents +1.00 of your DNA

Each of your living parents, siblings, or children represents +0.50 of your DNA

Each of your grandparents or grandchildren represents +0.25 of your DNA

Apply the scores above to each of your living relatives and sum the total.

What is your score? 🤔

I score 3.0

Quite easy to chart your life and I suspect this is a strong predictor for life outcomes, happiness, depression, etc. This is a very grounding / reflective little exercise.

(Could do +0.125 relatives, but keeping it simple for now)

Nope.

1. Your DNA and your parents' or grand-parents' are similar to a very high level but not identical. This is because of the mutations accumulated at each replication. So more like +0.499999 with your parenta for example.

2. Also, the 'liveliness' of your DNA would have to take into account epigenetic changes across generations.

3. Your grand-parents DNA exist in multiple copies in people of your generation (admixture). Your cousins for example. So more than 0.25 for sure.

But the beauty of genetics lies in these small rare changes that have tremendous effect in who we are and how we adapt to nature.
