Question

Imagine that a researcher is comparing the sequence of several protein-coding genes among mice, rabbits, and humans. She finds that, for most of these genes, the rabbit sequences are more similar to the human sequences than are the mouse sequences. What can she deduce?1. Mice and human share a more recent coomon ancestor than do rabbits and humans.2. More sequence are conserved between rabbits and humans than between humans and mice.3. No similar proteins exist in humans and mice.4. Mice and rabbits do not share a common ancestor.5. Humans and mice do not share a common ancestor.

Answer 1

More sequence are conserved between rabbits and humans than between humans and mice.

Step-by-step explanation:

HOPE THIS HELPS GOOD LUCK

Answer 2

More sequences are conserved between rabbits and humans than between humans and mice.

Step-by-step explanation:

That's the reason experimental trial of drugs or vaccines are first tested on rabbits.
