In the ongoing effort to determine just how much of who we are is preordained by our genetic code, heritability, a statistical measurement of how much variation in a trait can be attributed to genetic ...

1 The extinction vortex, is genetic variation related to extinction?; 2 How to measure genetic variation; 3 Inbreeding, geographic subdivision, and gene flow; 4 Genetic diversity in changing ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

New research suggests genetics account for up to 56% of lifespan variation, a significant increase from previous estimates. This shift is attributed to changing mortality patterns, with fewer deaths ...

Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...

Heritability isn't a fixed biological property but a measure that depends entirely on the population and circumstances you're ...
