Questions and Answers.
Mutation - Answer any change to the genomic sequence
3 neodarwinian population geneticists - Answer Ronald A. Fisher, Sewell Wright, Motoo
Kimura
Which of the following is not a research topic in population genetics
A) maintenance of genetic variation in time and space
B) the Hardy-Weinberg theorem
C) evolution of clines along environmental gradients
D) balancing selection involving lethal alleles - Answer B
Which of the following does not have to happen in order for the Hardy-Weinberg Theorem to
work?
A) population infinitely large
B) no mutation
C) mating is non-random
D) there is no migration - Answer C
Genetic Bottleneck - Answer creates random allele frequency changes that may decrease
fitness
What is not true about the founder effect?
A) its another variation of genetic drift
B) occurs when a few individuals become isolated from a larger population
C) can affect allele frequencies in a population
D) all of the above are true - Answer D
True or False. Rare alleles are likely to be lost during a bottleneck - Answer True
Genetic drift - Answer random change in the genetic composition of a population arising as a
consequence of sampling gametes from a finite population
