Question

examine the phylogenetic tree of several species of lizards.
which two lizards will have the most similar dna sequence?
○ desert iguana and western whiptail
○ fringe - toed lizard and horned lizard
○ fringe - toed lizard and zebra - tailed lizard
○ desert iguana and zebra - tailed lizard

Explanation:

In a phylogenetic tree, the closer two species are on the tree (i.e., the more recently they share a common ancestor), the more similar their DNA sequences are. The Fringe - toed Lizard and the Zebra - tailed Lizard are closer to each other on the phylogenetic tree compared to other pairs. This indicates that they have a more recent common ancestor, and thus their DNA sequences are more similar.

Answer:

Fringe - toed Lizard and Zebra - tailed Lizard.
