What's the diff between heritability and inheritability?

• mjburgess 2y ago
  They are entirely different. That's my entire point. Heritability doesnt mean inheritability. A trait is "heritable" only if it varies with the genes of some population, so a scottish accent is nearly 100% heritable. Heritability was a statistic invented for when the experimenter was in control of what genes were in what population (for breeding plants). It is meaningless when genes arent being controlled. Heritability is the idea that if you control which plant has which gene, and the plants are different, then it's probably because of the gene. But its applied to cases where no one is in control of the gene, so it's meaningless. When I said scottish accents are nearly 100% heritable, that's correct, as a matter of fact. If you compute the heritability stat for scottish accents it'd be nearly 100%.
