Why do queen honey bees (Apis mellifera) behave very differently from their workers even though a queen has essentially the same genome as her worker sisters and daughters? Develop at least one proximate hypothesis on why the two categories of bees behave so differently.

In the article called "Sexual dimorphism and male mating success in the tentacled blenny, Parablennius tentacularis (Teleostei: Blenniidae)" The sexually selected trait or traits in question. Based on what you gathered from the Article, What is the trait determining which individuals get to reproduce that the authors are interested in?

Assume that you are studying the evolution of anti-predator behavior in two species of butterfly. Both species A and species B have black and orange warning coloration on their wings that is used as a warning to predators. Which of the following studies would determine whether the warning coloration in species A and species B is a homology?     An evolutionary study that determines which species produces the warning coloration at a younger age.      An evolutionary study that determines if the same evolutionary forces maintain the black and orange coloration in both species.     An evolutionary study that determines which predators are affected by the warning coloration.     An evolutionary study that reconstructs color on the larger butterfly phylogeny to determine if the common ancestor of species A and species B also had black and orange warning coloration.

Alzheimer's is believed to be caused by a dominant allele, however, it continues to persist in populations, even though it is deleterious.  Explain why the allele for Alzheimer's  persists using an evolutionary justification.
