Question

Quizplus · Accepted Answer

The researcher is observing three traits: seed shape (round/wrinkled), pod color (yellow/green), and stem height (tall/dwarf). Each trait has two possible variations (round or wrinkled, yellow or green, tall or dwarf), resulting in a total of 2x2x2=8 possible phenotypes. However, since each individual plant can only have one variation for each trait, the actual observed phenotypes will only be a subset of the possible 8. Therefore, the researcher is observing three traits with two possible variations each, for a total of six observed phenotypes.
