Selfish Gene Theory

[Mudhammam]

Oh I see.
By regulatory genes I mean a gene "involved in controlling the expression of one or more other gene," like hox or pax genes. These are the genes that make all mammals vertebrates, with four limbs, two eyes, etc.
And specialized genes would include features like eye color, hair color, fitness, etc.

Oh alright. Yea it depends on what chromosomes they're on. Best to look at classifications as just a way human organize stuff instead of an actual manifestation of reality, it's often not a dichotomy but a mixture of everything because biology is a really messy science.

Thanks! Yeah I'm finding out that whatever spectrum of the sciences I try to learn about, from the very small to thevery big, it is pretty messy! You could probably make some very informative YouTube videos for those of us trying to come up self-taught.
