(07.05 mc) if there is a mutation in a zygote, where is it likely to be found in the fetus? (2 points) the mutation will show up in any fetal cells formed by mitosis but not in those formed by meiosis. the mutation will only be in the one cell that was the original zygote and the other cells of the fetus will not have it. the mutation will occur in all the cells of the fetus since they all formed by mitosis from the zygote. the mutation will only be found in the types of cells in the fetus that are formed by meiosis.

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection
