According to the American Anthropological Association, “race” is

1. the product of natural selection occurring over thousands of years
2. a group of people defined statistically by clusters of linked genetic traits
3. a biological classification based on the presence or absence of specific genetic traits
4. a social classification that is often assumed to have a biological basis
5. a clearly defined biological breeding population

Lactose tolerance in adults is

1. universally present in all human groups
2. due to a combination of genetic and environmental factors.
3. a recessive allele
4. determined purely by genetic traits

Intelligence tests

2. are culturally biased
3. can discriminate between genetic and cultural factors in native intelligence
4. show no signficant differences in intelligence among human populations

The sickle-cell trait is

1. the result of genetic experiments gone awry.
2. always debilitating
3. present in all people of West African descent.
4. a genetic adaption to the malarial parasite

American racial categories are

1. applied to endogamous breeding populations
2. based on DNA testing

Biological variation in human populations is

1. correspond to the major continents
2. easily sorted into 3 or 4 major groups
3. show continuous clinal variation across space
