Such a trade-off may well be at the basis of the genetic correlation between flowering time and cell wall biosynthesis observed in maize.
It is therefore possible to statistically control for genetic correlations that are built into different RI sets.
The genetic correlation is a statistic that indicates the extent to which the same genetic effects influence two different traits.
We chose a conservative approach, setting, the expected genetic correlation among DZ twins, to 0.5 and used the standard twin analysis path.
This indicates a possible genetic correlation since all human brains have the same general anatomical make up.
"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.
Additionally, some of these genetic correlations that shape behavioral syndromes can evolve.
The reason behind the choice for specialisation is the negative genetic correlation between the ability for dressage and show jumping.
Estimates of a genetic correlation obviously require a genetically informative sample, such as a twin study.
