Genes aren’t a good way to explain most things. They’re more like LEGO blocks. It’s how the cells use and express the genes that matters.
So you want to look at regulatory regions of the genome, promoters, and even how and when the dna folds up to inactive large regions. That’s where all the action is.
- iguy 6y agoThere are two meanings to "gene" here. What you describe as lego blocks are segments which code for a protein, which is one meaning. The other is just any code which affects the phenotype, including promotors etc. The SNPs mentioned in TFA are just known fairly common single-point differences, but aren't necessarily in coding DNA. Of course these are still heritable, just like coding changes.
