Ultraviolet (UV) visual sensitivity in animals has implications for mate choice, social signaling, prey detection, and foraging in general. Research into the genetic basis of the ability to detect ultraviolet light reveals that:
Select one:
a. this ability is the product of complex interactions among many gene loci.
b. sensitivity to UV appears to involve a single amino acid substitution in a visual pigment molecule.
c. the relative rarity of UV sensitivity among animals is attributable to the fact that multiple modifications of the visual pigment molecule promoting UV sensitivity are necessary to allow the detection of high-energy light.
d. UV-sensitive organisms are all descended from a common ancestor.
e. where genes coding for visual pigment molecules become integrated, they can vastly extend the spectrum of the photosensitive pigment produced.
