Which condition can lead to two populations becoming different species? all of these A barrier to gene flow exists between the two populations. Individuals in the two populations have significant genetic differences from one another. Individuals may live in geographically isolated areas. Individuals in the two populations mate at different times. Which of these is NOT an example of adaptive evolution? bottleneck all of these gene flow founder effect Mutation Which of these does NOT influence allele frequencies in a...

Fifty years ago, the entire species of the Galapagos Island tortoise Chelonoidis hoodensis consisted of only 12 females and two males. It was recently found that one male named Diego fathered 800 offspring, which now account for 40% of the entire species. This is a very happy story except for the following.

Which of the following statements about genetic drift as an evolutionary factor is true? a. It is more potent in a population with small numbers than in a population with large numbers. b. It is responsible for the selection of mutations. c. It is connected to the movements of alleles between populations of a single species. d. Its strength is proportional to the size of a population: the larger the population, the greater the force. e. Both a and b
