Identical twins having extremely similar faces isn’t exactly a great argument for determining facial characteristics via dna, as identical twins also shared the same environment during fetal growth. It’s entirely possible that genetics and developmental experience combined creates facial structure, and that dna alone is insufficient.
- iguy 6y agoI guess you should compare to non-identical twins. Who I think look like siblings who happen to be the same age. But no doubt someone somewhere has tried to quantify this.
- BurningFrog 6y agoFair point. The only experimental way I can think of checking this is how similar cloned animals are. A quick googling seems to say clones are quite similar, but not really identical. Which I think somewhat contradicts my claim.
