Intro Bio 151/3 Discussion Please answer the following questions before coming to discussion the week of April 21 to 24. No dropbox submission required this week. In discussion we will work on any problems you have questions about. Following that we will work on additional problems (to be provided in discussion). 1 to 3. Hardy-Weinberg Principle -- Test your understanding In each of the following scenarios, choose which assumption of the Hardy-Weinberg Law is being violated. 1. In a particular region of the coast, limpets (a type of mollusc) live on near shore habitats that are uniformly made up of brown sandstone rock. The principle predators of these limpets are shorebirds. The limpets occur in two morphs, one with a light colored shell and one with a dark colored shell. The shorebirds hunt by sight and are able to see the light ones on the dark sandstone easier than the dark ones. No Selection – The shorebirds are selectively taking the most visible (light) limpets. 2. In Chen caerulescens (a species of goose), the white body form, the snow goose and the blue body form, the blue goose, occasionally coexist. In these areas of contact, white by white and blue by blue matings are much more common than white by blue matings. No random mating – In areas of overlap, there is little genetic mixing between white and blue
