Which of the following statements about the development and function of the visual system in animals is INCORRECT?
A)The light-sensitive molecule for all light-sensing cells is the same, a derivative of vitamin A complexed with a protein called opsin.
B)Eye defects arise from Pax6 mutations in many different organisms.
C)Pax6 DNA and protein sequences are highly conserved in a wide range of organisms.
D)Pax6 protein is so central to eye development that after transferring the mouse Pax6 to the fruit fly, the fly produces eyes similar to that of a mouse.
E)The Pax6 gene evolved early and is shared among a wide range of animals, despite the structural diversity in their final adult eyes.

Question

Quizplus · Accepted Answer

The incorrect statement is D because transferring the mouse Pax6 gene to a fruit fly does not make the fly produce eyes similar to that of a mouse. Instead, it can induce the formation of fly-type eyes in various body locations, demonstrating the gene's role in eye development across species but not leading to the development of mouse-type eyes in flies.
