Dozens of Potato Varieties Exist, Differing from Each Other in Potato-Tuber

question 28

Multiple Choice

Dozens of potato varieties exist, differing from each other in potato-tuber size, skin color, flesh color, and shape. One might construct a classification of potatoes based on these morphological traits. Which of these criticisms of such a classification scheme is most likely to come from an adherent of the phylocode method of classification?

• A)Flesh color, rather than skin color, is a valid trait to use for classification because it is less susceptible to change with the age of the tuber.
• B)Flower color is a better classification criterion, because below-ground tubers can be influenced by minerals in the soil as much as by their genes.
• C)A more useful classification would codify potatoes based on the texture and flavor of their flesh, because this is what humans are concerned with.
• D)The most accurate phylogenetic code is that of Linnaeus. Classify potatoes based on Linnaean principles; not according to their color.
• E)The only biologically valid classification of potato varieties is one that accurately reflects their genetic and evolutionary relatedness.
