Question

This phylogenetic tree was constructed by comparing sequences for a homologous gene involved in development. Select the correct statement.a. Frog is the ancestor of both a mouse and a chicken. b. The common ancestor of a human and a frog and the common ancestor of a mouse and a chicken lived at the same time. c. The nucleotide sequence of this gene in a mouse is more similar to the sequence in a chicken, and both are less similar to the nucleotide sequence of this gene in a frog.

Answer 1

Answer: c. The nucleotide sequence of this gene in a mouse is more similar to the sequence in a chicken, and both are less similar to the nucleotide sequence of this gene in a frog.
