When the Pax6 transcription factor is transferred from a donor individual of one species into the genome of a recipient individual of a different species, it:
A)usually has no detectable effect.
B)represses eye development.
C)induces the development of eyes similar to those in the donor species.
D)induces the development of eyes similar to those in the recipient species.
E)induces the development of eyes intermediate between those in the donor species and those in the recipient species.

Question

Quizplus · Accepted Answer

Pax6 is a highly conserved transcription factor across species that plays a crucial role in eye development. When transferred from one species to another, it induces the development of eyes characteristic of the recipient species, not the donor species. This demonstrates the conserved function of Pax6 in eye development across different organisms.
