(3) You are interested in understanding the genetics of coat color and hair length in dachshunds, which have one of 2 primary colors (brown and black) and either long or short hair. You cross a pure-bred black long-hair dachshund with a brown short-hair dachshund, and all of the offspring are black with short hair. When you intercross these offspring, you obtain the following phenotypic ratios: 44 black short hair dachshunds 23 black long hair dachshunds 21 brown short hair dachshunds (a) Perform a statistical test to determine if these data support a hypothesis of Mendelian inheritance based on independent assortment. (4 points) (b) If you reject the null hypothesis of Mendelian inheritance, propose an alternative hypothesis. How specific can you be in your hypothesis? Explain the limits to the conclusions you can make given these data alone.
