of the following statements about mutations is not accurate? overall advantage to the e commonly found in a population where it provides B) Harmful mutations occur frequently but they are selected for and, therefore, these mutant alleles are extremely common. c) Harmful mutations occur frequently but they are selected against and, therefore, these mutant alleles remain extremely rare. d) Beneficial mutations occur less frequently but they are selected for and therefore, these mutant alleles accumulate over time. 21) Speciation can be defined as which of the following: a) Evolutionary change that happens at the species level. (b) The formation of a new species. C) The occupation of different habitats by different species. d) Different species use different signals to attract a mate. 22) This occurs when two or more species evolve increasingly different traits, resulting from differing selective pressures or genetic drift. a) convergent evolution (b))divergent evolution c) allopatric speciation d) sympatric speciation 23) When populations split into different gene pools and continue to share a similar geographic location. a) convergent evolution b) divergent evolution c) allopatric speciation (d) sympatric speciation 24) When two populations become geographically isolated from one another and individuals can no longer migrate between populations. a) convergent evolution b) divergent evolution (c) allopatric speciation d) sympatric speciation L25) If a population consisted of 450 individuals and an evolutionary biologist was studying this population and observing the gene frequencies of a simple dominant/recessive trait found in the population , what is the total number of alleles the biologist would find in the entire population? a) 450 b) 225 (c)/900 d) 1800
