    On a side note, isn't it somewhat unhelpful to put personality connotations to this as hero vs philosopher. I mean afterall at the end of the day it is about stimulation, and I am sure a lot of famous philosophers could've been both (worriers and warriers and in between). I think Philosophy, if going by the card sorting analogy, requires both kind of people.

    I find the assumption of additive dominating a bit strange. Whenever I studied specific genes whose mechanism of action is known (e.g. that protect plants from drought) their effect is massively dependent on other genes and the environment. I fear that scientists assume interactions don't matter because it'd be almost impossible to study this if they did, so it's convenient to pretend they don't matter.

    • @behaviouralgenomics438

      For polygenic traits it is simply not feasible to do so. Especially when you are dealing with associated SNPs and not a known causal mechanism.

I read a paper ages ago (sadly forget the title) about how the desire for things to be mathematically or empirically tractable leads scientists astray sometimes. I hope additive influence dominants though, i want it to be testable !

    I'm a homozygous worrier and I feel like I have more "patience" with monotonous and mundane activities. I can even feel a slight pleasure in doing repetitive activities, how crazy is that! Even though I'm homozygous, I feel like I can react well to mild or moderate stress situations. However, at the same time I have had Post Traumatic Stress at work, I have anxiety and depression. I take the antidepressant venlafaxine and it has helped me a lot with my anxiety, my psychiatrist said that it regulates Dopamine.

      a interest contrast is there is one co-worker who def has the worrier variant and the pros is he never forgets anything that needs to be done throughout the day while ill miss things like making gravy as an example, nothing like that gets passed him. but when it gets busy he does shutdown and goes into a quiet support role like taking care of putting bread for a clubhouse into the toaster and filling up sauce cups for the next order coming up, its actually nice combo we got going on line when together

      There is a large literature about the moderating effect of gender on the associations between COMT polymorphisms and behaviour. To include it would have made the video too long. Oestrogen also regulates prefrontal cortical dopamine so there is certainly an interaction between sex and COMT status.

      I am sorry for your trials and I hope things are better for you now. You may enjoy reading The Neuroscience of Addiction and Blueprint How DNA Makes Us Who We Are. The common thread of both texts is that genetics build more of our basis than many people are comfortable admitting. The second book states that genes are probabilistic, not deterministic. However, such probabilistic genes can push people towards certain behaviors and outcomes.

    Phenomenal video!!! Thank you for drawing the connection between linkage disequilibrium and haplotypes. The absence of this connection increases confusion when texts explain LD blocks (haplotypes) that ARE associated with diseased alleles. It’s easy to question “just because two alleles are linked doesn’t mean a diseased allele is nearby, right?”, but the fact that linkage disequilibrium creates haplotypes/LD Blocks makes this much more reasonable to understand how these haplotypes can indicate diseased states. Having this said, without actually genotyping the intervening exons and introns… how can we say for certainty the haplotype is pure to the reference and isn’t experiencing an alternative mutation?
