On a hike through the forest, you notice a population of 100 flowering plants that all look identical (phenotypic clones), and they span an area of approximately 100 square meters. You take some representatives from one corner of their distribution back to the lab, sequence their DNA, and conclude that they are also genetic clones (i.e. genetically identical). Based on this information, state whether the statements below are true or false.

Also, provide an explanation.

1a. True or False: This population can evolve by natural selection.

1b. True or False: This population can evolve by genetic drift.

Answer:

1a. False

1b. False

Explanation:

They are genetic clones which make them identical so there is no difference in phenotype which is the key mechanism for evolution to occur through natural selection.

- since they are of one phenotype(genetically identical) genetic drift can not occur. For genetic drift to occur, there must be a change in the frequency of one allele within a population over a period of time and this genetic variation must occur randomly for a genetic drift to occur.
