Swarthmore College. If we understand the physical connection between magnetic fields in massive stars and X-rays, we could use X-ray observations to identify magnetic massive stars.. e.g. Which of the stars in this Chandra X-ray image of the Orion Nebula Cluster are massive magnetic stars? . 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. 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.

Misunderstandings in MZ twins. “Estimates of heritability of liability to a number of diseases turned out to be quite high. This was a surprise to those not versed in quantitative genetics who tended to think that low concordances rates in MZ twins implied low heritability.” Fraser (1976) . Associate Professor.
