Which source of molecular data would be most helpful for a study of the evolutionary relationships of closely related species of flies?
A) Chloroplast DNA
B) Mitochondrial DNA
C) The amino acid sequences of a protein found in all animals, such as cytochrome c
D) Ribosomal RNA sequences
E) Epigenetic markers that are due to environmental conditions

Question

Quizplus · Accepted Answer

Mitochondrial DNA would be the most helpful source of molecular data for a study of the evolutionary relationships of closely related species of flies. Mitochondrial DNA evolves rapidly and is maternally inherited, allowing for the detection of subtle genetic differences between closely related species.
