A lot of experts have a vague understanding of heritability (H2).  They know that heritability is the phenotype correlation between genetic clones randomly separated into different enviornments, but what not even the World’s leading experts on heritability seem to understand is what the H in H2 means. They make statements that show they are clueless about which of these three statements is true and why:

H = phenotype-genotype correlation

H > phenotype-genotype correlation

H < phenotype-genotype correlation
