Document Summary
Biol 2153, sections 1-4, dr. foltz, principles of genetics, spring 2012, homework #2. Some review questions on statistical analyses of dihybrid data. Mendel"s dihybrid cross is reprinted below: parental generation: yellow round x green wrinkled. Considering all the material above the dotted line, draw a solid line around all of mendel"s data. The column of numbers 315 through 32 are the data. Also, draw a dashed line around all of mendel"s experimental design. The two crosses symbolized by the two the dark black arrows are the design. Fill in the four blank columns at the right in the above table with the appropriate values. There are always 3 degrees of freedom if there are 4 phenotypes. ___ 7. 82_______ this value always comes from a table look-up. Random chance alone can explain the observed deviations of the observed numbers from the expected [or predicted] values that were derived from mendel"s laws of independent assortment and segregation.
