Pax-6 is a gene that is involved in eye formation in many invertebrates,such as Drosophila.Pax-6 is also found in vertebrates.A Pax-6 gene from a mouse can be expressed in a fly,and the protein (PAX-6)leads to a compound fly eye.This information suggests which of the following?

Question

Quizplus · Accepted Answer

The fact that a Pax-6 gene from a mouse can be expressed in a fly suggests that the gene is highly conserved and shows shared evolutionary ancestry across invertebrates and vertebrates. This does not necessarily mean that the Pax-6 genes have identical nucleotide sequences or that the PAX-6 proteins have identical amino acid sequences, and it also does not suggest that the proteins are different for formation of different kinds of eyes.
