The Upper Midwest, because of its numerous shallow lakes and marshes, rich soils, and warm summers, is described as being one of the most important wetland regions in the world. The area is home to more than 50% of North American migratory waterfowl, with many species dependent on the potholes for breeding and feeding. In addition to supporting waterfowl hunting and birding, prairie potholes also absorb surges of rain, snow melt, and floodwaters thereby reducing the risk and severity of downstream flooding. Statewide, elevated levels of phosphorus have been found in 31% of our āprairie potholeā wetlands, negatively affecting the insects, snails, and leeches that live there. How has this elevation in phosphorous LIKELY impacted the biodiversity of the prairie potholes in Minnesota?

In the california poppy, an allele for yellow flowers (c) is dominant over an allele forwhite flowers (c). at an independently assorting locus, an allele for entire petals (f) isdominant over an allele for fringed petals (f ). a plant that is homozygous for yellow andentire petals is crossed with a plant that is white and fringed. a resulting f1 plant is thencrossed with a plant that is white and fringed, and the following progeny are produced: 54 yellow and entire; 58 yellow and fringed, 53 white and entire, and 10 white andfringed. using the chi-square test, what would the probability value (p-value) be?
