Chapter QUANTITATIVE GENETICS: MEASURING HERITABILITYIntroductiondemonstrations that traits which are normally distributed can arise from the action ofmultiple genes, each with relatively small effect RACE, IQ AND HERITABILITY 583 son jumped the gun, and that a closer look at the texts resolves the problem in a way that does not necessitate a speculation about Jensen's political motives. More gener (Falconer & Mackay: chapter 10). Sanja Franic. VU University . Amsterdam 2012. ‘like with like’. reflected in a phenotypic correlation between mated individuals. mating in human populations is assortative with respect to many characteristics, such as stature and IQ. A) is the proportion of genetic variation that is due to phenotypic variation. B) is a property of an individual, not a population. C) means that the trait is genetically based. D) can be measured from the resemblance among relatives. 1. ) A bit of basics. 2) Heritability (Ch 10). 3) Assortative mating (Ch 10). 4) Homework. 5) Questions, thoughts?. A bit of basics.
