Human Variation: Population Genetics

Front 1

The impact gene drift alone (without effects of other evolutionary forces) has in
causing allele frequencies changes depends on what?

Back 1

Chance and size of population.

Front 2

The influence mutation alone has in causing allele frequency changes depends on what?

Back 2

Frequency of mutation and size of population.

Front 3

The kind of malaria that is usually associated with sickle cell anemia is

Back 3

Falciparium Malaria

Front 4

Maintaining a relatively constant body temperature, despite variations in ambient
environmental temperature, is called

Back 4

thermo-regulation.

Front 5

(two words) mating is
mating choices based on a trait that is different in the members of the pair.

Back 5

Negative assortative mating

Front 6

Within a single species, the most darkly pigmented members of the species occur in
the warmest, most tropical part of the species’ range. This is called?

Back 6

Gloger's Rule

Front 7

Selection occurs as a double “whammy.” It happens when there are differences in?

Back 7

Mortality and fertility.

Front 8

There are several anatomical structures that produce skin pigmentation. List two of
them.

Back 8

Melanocytes in the stratum germinativum and keratin in the stratum granulosum.

Front 9

List three characteristics of polygenic traits (not examples of the traits).

Back 9

They are inherited at more than one loci, there are many alleles, continuously distributed, quantitative, environmentally influenced.
