"It wasn't consistent with the idea of genetic correlation driving female brightness," Dr. Hill said.
It could still be a result of genetic correlation with the male.
More than one study has demonstrated a genetic correlation between I. Q
Last, GREML and LDSC can be used to explore the genetic correlation of traits14,15.
The genetic correlation between length and weight was high (0.97).
The maximum likelihood estimate of the genetic correlation was −.63.
Keller, M. C. et al. The genetic correlation between height and IQ: Shared genes or assortative mating?
Other signs that genetic correlation may not be the whole story come from studies of changes in male and female coloration in some bird species over evolutionary time.
But the estimated genetic correlation between the two traits was one — that is, perfect — or at least as close to perfect as you can get.
We also found a potential pleiotropic QTL between development time and size at metamorphosis that, if confirmed, might underlie the previously reported genetic correlation between these traits.
In New York and New Orleans, rats showed the highest genetic correlation within 500 yards of one another, beyond which rates of shared DNA dropped precipitously.
