Gene genealogies can vary for different loci. What does this imply for species trees? Group of answer choices
hodyreva [135]

Answer:

The correct answer is option B) "Species trees should be constructed using multiple loci (both nuclear and mtDNA)".

Gene genealogies could not be established using an unique genetic loci, since not always the same loci vary among individuals. Therefore, species trees should be constructed using multiple loci (both nuclear and mtDNA), to avoid erroneous inferences obtained by analyzing loci that do not vary among individuals.
