The vertebrate pax-6 gene product (the pax-6 protein) triggers a complex program of gene expression resulting in formation of the vertebrate eye, which has a single lens. the fly pax-6 gene leads to formation of the compound fly eye. when scientists cloned a mouse pax-6 gene and introduced it into a fly embryo, it led to formation of the compound eye of a fly. what did scientists induce from this? the vertebrate pax-6 gene product (the pax-6 protein) triggers a complex program of gene expression resulting in formation of the vertebrate eye, which has a single lens. the fly pax-6 gene leads to formation of the compound fly eye. when scientists cloned a mouse pax-6 gene and introduced it into a fly embryo, it led to formation of the compound eye of a fly. what did scientists induce from this?
