Document Summary

If we examined your karyotype, we would find that your alleles for hair are. Estimate of how much observed variability is due to genetic factors alone. When h2 = 0. 0 (due to environment) h2 = 1. 0 (due to genes) Does not indicate extent to which genes are responsible for expression of trait. Taps relative contribution of genes to overall variation in population. Heritability is only implied within group you"re looking at cannot compare groups. When everything is the same, h 2 = 0, but genes are responsible for expression of hair colour h2 increases as genetic diversity (as there are more karyotypes) increases h2 decreases as environmental diversity increases. Similar medical history, liked math, hated spelling, same dog names, habits etc. Oskar raised by catholic family in germany; jake by jewish family in israel. Similar habits: two-pocket skirts, liked spicy foods etc. Believes that intelligence was unitary (could be captured by one thing - mental quickness)
