reletively yes but you still shouldn’t.

a 1st cousin has like 16% shared dna. half removed is half that. 2nd cousin is half of the half removed and it repeats.

so 1st > 1st half removed > 2nd > 2nd half removed> … nth.

after a few steps in your percentage is already pretty fucking low.

Iirc first cousins have a 5% chance of terrible outcomes, which might sound low but… anyone who has played D&D or other d20 TTRPGs know how often 1s hit.

All humans have like 99.9% shared DNA with every other human on a planet. Hell we have about 50% shared DNA with a banana.

  I assume the 16% is of the portion of DNA which varies among humans, not the shared portion which makes one human in the first place.

    No no, I think he’s talking about cross-species cousins
