It has to increase in size and make extra proteins to get ready for division <span />
Answer:
The chart shows how well each beetle with each trait were able to survive in their environments, and Mutant 1 was clearly out living the other two, because as you can see mutant 2 has only last for at least one generation, while the non-mutated one lived a little longer. This is because Mutant 1 developed the trait that made its shell darker, and thus it's easier for them to hide from predators, and they were able to successfully pass on their genes to their offspring so now they can do the same.
The correct answer is: Hares with a mutation that causes them to change color in response to temperature rather than day length
Since the climate is changing (as a consequence of global warming) temperatures are increasing more and more through the years. These changes affect populations, so they need to adapt to new environment conditions in order to survive. In this example above, mutations within snowshoe hares that will help them to change color in response to temperature rather than day length is very advantageous. Hares will be brown more often, because there are less and less colder temperatures and snow.
The PAX-6 gene is a gene that translates to the PAX-6 protein that serves as a transcription factor needed to activate certain genes that functions in the development of the eyes. While PAX-6 gene may look like it produces different functions for different species (such as formation of the compound eye in insects vs. formation of a single lens eye in vertebrates), it does not. It does in fact only regulate the genes required for the formation of the eyes. Absence or mutation of the PAX-6 gene will cause aniridia or absence of the iris, opaque lens and cornea, and a dysfunctional retina. Also, the function of the PAX-6 protein is conserved throughout evolution of species.
