Card 12 / 112: When comparing two populations of a plant species, a biologist observes that one population's root size is significantly different. Can she conclude that the species are diverging and have different genetic traits? Why, or why not?
A) Yes, her results show significant differences between the two populations
B) Yes, she must compare the environmental differences between the populations to determine if the difference is one due to plastic phenotypes of the species or if the difference is genetically based.
C) No, significant difference in traits between populations is always genetically based.
D) No, she must compare both the genetic and environmental differences between the populations to determine if the difference is one due to plastic phenotypes of the species or if the difference is genetically based.
