Talk:Gene-centered view of evolution

Interchromosome competition is one of the more fascinating aspects of gene-cenetered evolution. Where male "y chromosome" genes have a different "optimal" behaviour than "x chromosome" genes. There are these mice....gotta find them brb. tmtoulouse 05:09, 16 January 2010 (UTC)

I have to go take a walk because the nonsense here is driving me up the wall. Feel free to do what you like to clean up/delete this article. My only reason to create it was to get away from the bullshit. My expertise is more in chemistry than biology so apologies if I didn't hit the nail on the head. I think I'm in the ballpark, though. δ_ij$^{i.broke.it.}$ 05:11, 16 January 2010 (UTC)

Nice works. The bullshit was an accident, sadly RW is so easy to troll that even unintentional trolls can do it. ħuman 05:17, 16 January 2010 (UTC)

Its a fascinating topic I will probably come back to it when I have not had too much to drink. The mice I was talking about are Peromyscus maniculatus (polygamous) and P. polionotus (the monogamist). They are two different species with two different mating patterns (highly polygamous versus monogamist). The males in the polygamous society value the "future reproductive success" of the mother far less than the current offspring. The monogamist future offspring are almost as valuable as current. So in the polygamous mice there is a gene on the y chromosome that tries to over extract resources, and an x chromosome gene that has evolved to try and suppress it. This is an evolutionary red queen race between chromosomes in the same animal.

Whats really interesting is that the polygamous mice and the monogamist mice can interbreed. What happens if you breed a male polygamous with a female monogamist you get really big big babies since the male gene is over extracting but there is not offset in the x chromosome. If its a polygamous female and monogamist male you get tiny babies since the x chromosome gene is over compensating with out a y chromosome trying to extract resources.

This all falls out of Haig's theory about competition between offspring in the mom and future offspring that might be present. The fetus wants "more" form the mom than the mom wants to give. So you get some crazy evolutionary arms races. You get these massively complex signaling proteins for resources in the fetus. Way, way, way more complex than is needed. The hypothesis is that the fetus "cries" for more resources and the moms body learns to "ignore" the cry and try and provide only the minimum. So there is pressure on the fetus to cry "louder" and the mom to ignore more. And you get this massive build up in signaling.

Its all about the red queen race, love this stuff. tmtoulouse 05:24, 16 January 2010 (UTC)

That does sound fascinating, Trent. Make it happen.

Yes, when you're sober, write that red queen race thing, if you're up to it. ħuman 05:33, 16 January 2010 (UTC)

Is my attempt at an explanation not completely inept? I'm worried that I didn't get it fully correct. δ_ij$^{i.broke.it.}$ 05:29, 16 January 2010 (UTC)

I'll do some research and try to find some better sources. Tetronian ^{you're clueless} 13:45, 16 January 2010 (UTC)

LOL, better than none? That may be tough...good luck with that. (As per my usual, I didn't bother to look anything up. "Facts" are liberal-contrived bullshit anyways.) δ_ij$^{i.broke.it.}$ 15:50, 16 January 2010 (UTC)
