Data Set 14-1: With tomatoes, the color of the fruit and the height of the plant are genetically determined (with red dominant over yellow, and tall dominant over short). Suppose for a few minutes, that you are a geneticist during the 1920s or 1930s when these facts are unknown. If the above theory is true, a particular set of crossings will result in a 9:3:3:1 ratio, with nine tall reds to three short reds to three tall yellows to one short yellow.
-The investigation in Data Set 14-1 is one
A) of independence
B) of goodness of fit
C) that could be either
D) that will require combining categories due to the two 3's and a 1.

Question

Quizplus · Accepted Answer

The investigation is of goodness of fit because it involves testing whether the observed genetic ratios fit the expected 9:3:3:1 ratio based on Mendelian inheritance.
