Question

The PAX6 gene is involved in eye development, and when inserted into the genome of an eyeless mutant fly, it will likely express in the developing fly eyes. This would result in fly eyes forming wherever the gene is expressed, potentially leading to the formation of compound eyes in the normal location as well as other areas.
