Genetics and epigenetics is relevant in a project I'm doing but it's the first time I've learnt about genetics in any capacity so it's been a slower process. I've been at it for over a week and I'm struggling to find an answer to what I presume has been left out by reports because it's assumed knowledge. I'd really appreciate any insight on these questions, or linking me a resource that fleshes any of them out. Thanks a lot. Do we all have the same genes but it's just our alleles that are different? Like we need to have a gene for x but we have slight variations in whatever fills x's purpose? This is an especially silly question but I just haven't got the prior knowledge to justify assuming. Are all environmental factors that influence something about us epigenetic factors? Or can our environment change something about us without affecting gene expression? I'm assuming of course they can but it's confusing me a little bit. Do genes affect reward pathways?…
