`Lewontin claims that equation (1′)(1′) above presents the most accurate picture of the contributions to phenotypic variance. He goes on to argue that VI,VG×EVI,VG×E and COV(G,E)COV(G,E) are not negligible. In fact, he argues that these are always part and parcel of the variance in traits. As a result, apportioning the phenotypic variance between genes and environment is no easy matter and standard analyses of variance simply cannot come up with useful and informative values for h2bhb2 and h2h2. `

soft science lol

Listen, yo. Maybe there are neuron elves which help on IQ tests in some environments and not others. So we've got to toss out all your highly correlated genetic IQ data.

Sociology TM

"reading to your kids makes smart kids", or it's just the fact that smart parents read to their kids that inherit their intelligence

I know a lot of stupid people who read novels like crazy

@BabygottBach that quote is meaningless without context

lol

`Finally, VPVP can be effected by non-random correlations between genotypes and environments referred to as gene-environment covariation, COV(G,E)COV(G,E). For example, if plants with a genotype that tends to produce large plants also select nutrient- rich environments and plants with a genotype that tends to produce small plants also select nutrient- poor environments, the variance in height would be increased. If the relation was switched the variance would decrease (Futuyma 1998). `

I still would like you to explain why twins keep performing similarly across measures and studies @BabygottBach

there's that @Deleted User

@BabygottBach Blacks underperform whites worldwide

@Nerthulas, I'm not familiar with the sociological research on this matter.

Let's try them in the vacuum of space

Nigga I can't understand these snippets of a paper without the context

So you trust it with no knowledge?

What's the replicability rate of the GCTA?

@Deleted User, nope

@BabygottBach get in vc

ok but the environments are different so why are the twins performing the same across measures and studies @BabygottBach

I dont trust either side with no knowledge

can you please explain this to me

At this glance, it seems like there's a huge debate between two camps

I just want you to explain why the twins perform the same

Do you think parents treat twins exactly the same?

The overarching point is that there are variances and I don't give a fuck exactly how they exist 😆

Sociology TM

well, its consistent across all measures and studies

Look up the twin niching effect, @Nerthulas

but its consistent across ***all*** twin studies

Sexual reproduction causes the shuffling around (recombination) which breaks the epistasis so it actually isn't the death toll for heritability estimates or quantitative genetics

Maybe there's a consistent sociological effect, @Nerthulas?

if they didn't treat them the same, wouldn't that make them score differently?

A confounding sociological variable.

that's the opposit eof the claim

but its different from the other siblings @BabygottBach

"Parent may treat their twins differently by 1/10,000th of a degree, therefore ambiguity on heritability

lmao

so they are more alike to each other than to people they share environment with

omg you guys are still at it

can you explain this?
