Exam 22: Population Genetics and Evolution

If an Ashkenazi carrier and a French-Canadian carrier had a child,what are the chances that they would have a child who is a carrier for both types of the mutation?

Which aspect of population genetics can lead to changes in allele frequencies in a new mixed population following migration?

If the frequency of PKU,an autosomal recessive disease,is 1% in males,what is the frequency of females with PKU?

Both the founder effect and the bottleneck effect are mechanisms that produce large allele frequency sampling errors in a small population due to

In a theoretical population where f(A₁)= 0.95 and f(A₂)= 0.05,µ = 1 × 10⁻⁶,and v = 1 × 10⁻⁷,what is Δq?

If the genotype frequency in an admixed population is f(A₁)= 0.75,what is the genotypic frequency of heterozygotes in the admixed population?

A relative fitness value of w = 1 means an organism exhibits what trait?

Which mechanism maintains the biological ability of populations to interbreed and can thus prevent evolutionary divergence of populations?

In a group of 500 people,the frequency of genotype NN is 40%.How many individuals would you expect to have the MN genotype?

In CODIS,what type of genetic marker is used to predict population genotype frequencies?

Using the allele frequencies in the table below,what is the probability that a random person would be heterozygous 12/14 for VWA?

If the frequency of hemophilia,an X-linked recessive disorder,is 10% in males,what is the frequency of carriers in the population (both males and females)?

Of the five aspects of Hardy-Weinberg equilibrium,which one directly affects phenotypic frequency rather than genotypic frequencies?

What is the ultimate source of genetic variation in populations?

When examining the effects of forward and reverse mutation rates,what equation is used to calculate the change in the frequency of A₂,or Δq?

The pattern of species evolution known as ________ is one of branching in which an ancestral species gives rise to two or more new species.

In an island population,the frequencies of the three MN blood types are given here: M: 550 MN: 725 N: 225 a. Calculate the allele frequency of M and N. b. Assuming random mating,what are the expected frequencies for each blood type? c. Use chi-square analysis to test your hypothesis that mating is random for this population.

Recessive mutations are subject to natural selection only when they are in the homozygous recessive genotype.What does this mean in terms of allele frequency?

A difference in allelic frequencies that is produced when a new population is established by a few individuals is known as what type of genetic drift?

If the relative fitness value is w = 0.6,what is the selection coefficient used to identify the differences between the fitnesses of organisms with different traits?
