1a. Imagine that you are a skeptical scientist who is not convinced that the phylogeny of animals is accurate. You wish to reconstruct the animal phylogeny using molecular sequence data. Which of the following genes would be the best choice?

a. genes involved in flagella development

b. genes for mitochondrial cytochromes

c. genes for collagen

d. genes for jaw development

1b. Explain your answer above and how you narrowed down your selection, including support for the correct answer and support against incorrect answers

Explanation / Answer

I would choose genes for mitochondrial cytochromes. These genes come from mother only, so it is possible to trace the phylogeny of an animal.

Hence, the correct option is (b) genes for mitochondrial cytochromes.

Other genes come from both parents, so they are not that much useful in accurate tracing of animal phylogeny.
