Exam 22: Population Genetics and Evolution

What are the two most common types of nonrandom mating?

The coefficient of inbreeding (F)can be used to estimate the proportion of loci that are

Which aspect of population genetics refers to chance fluctuations of allele frequencies resulting from sampling error and is more prominent in small,isolated populations?

You want to calculate the frequency of the allele causing sickle cell disorder in your patients,and you know the genotypes of every individual.Assuming the population is not in Hardy-Weinberg equilibrium,which method can be used to calculate allele frequency?

If the frequency of hemophilia,an X-linked recessive disease,is 10% in males,what is the frequency of females with hemophilia?

All Old Order Amish families from Lancaster County with Ellis-van Creveld syndrome can trace their genealogies to Mr.and Mrs.Samuel King,who immigrated to Lancaster County in 1744.This is an example of

Which two molecular techniques are used in DNA profiling to generate data included in the FBI's CODIS database?

In the same population of patients you examined for sickle cell allele frequencies,you now want to test whether the disease symptoms are related to blood type.Since blood type is a codominant trait and the alleles are easily identifiable by the phenotype (blood type)of the individuals,which method is most helpful for identifying blood type allele frequency?

Given the following genetic profile,how many individuals would remain after natural selection?

If an X-linked recessive trait has a frequency of 5% in males,what percentage of females are carriers?

If the heterozygous genotype is favored (as exhibited by the sickle cell allele in malaria-prone regions),selection results in a ________ in which alleles reach stable equilibrium frequencies that are maintained by the ongoing action of selection against the homozygous genotypes.
