Which of the following statements about reproductive migration between populations is untrue? Group of answer choices Migration between two populations results in making both populations less homogeneous Cultural differences between populations are a barrier to migration When migration is prevented, separate species can arise Geographic distance can produce reproductively isolated populations

Which of the following statements is false? Select one: a. The rate of genetic divergence between populations depends on the dispersal abilities of an organism, the geographic distance between populations, and whether or not there are any barriers to dispersal between those populations. b. If two isolated populations start with the same allele frequencies, genome-wide Fst will tend to increase faster if those populations are large than if they are small. c. Landscape genetics includes the study of how drift and migration affect the evolution of populations. d. Comparing F values between different genes can help identify loci that have diverged between those populations due to strong selection. e. Migration between populations should tend to make allele frequencies more similar between those populations.

Which of the following is false regarding speciation? A. Speciation usually occurs over many generations, with populations gradually diverging due to drift and/or selection until the are fully separate lineages B. Speciation (defined as reproductive isolation) can occur almost instantly – due to changes in chromosome #, for example C. If two recently diverged species come back into contact and hybrid offspring are inviable, there will be selection for differentiation in breeding signals D. If two groups are “good” species according to the biological species concept, they will also exhibit fairly clear differences in appearance or ecology

Which statement about speciation is not true? a. Speciation can occur rapidly or slowly. b. Developmental genes can account for rapid speciation. c. The fossil record gives no evidence that speciation can occur rapidly. d. Speciation always requires genetic changes, suc
