Using the attached figure, what statement is true? genetics382flowertreeexercise06.pdf 92 kb genetics382flowertreeexercise06.pdf 92 kb a. none of these statements are true. b. flowers on peak 1 and flowers on peak 4 are genetically identical. c. flowers on peak 1 and flowers on peak 2 are genetically identical. d. flowers on peak 1 are genetic ancestors of flowers on all other peaks. e. flowers on peak 3 are genetic ancestors of flowers on all other peaks

The correct answer is option B. "Flowers on Peak 1 and flowers on Peak 4 are genetically identical".

Explanation:

Phylogenetic trees are graphical representations of the relationships among species, at which the closer two organisms are, the closer they are put together in the tree. Modern phylogenetic trees are constructed based on the anaylsis of genetic material, usually mitochondrial DNA. In this case, flowers with different phenotype and genotype were classified in a phylogenetic tree. Since flowers on peak 1 and flowers on peak 4 are grouped together it is safe to assume that the two organisms are genetically identical. I attached the missing figure.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
