Question
Chapter 30, Problem 1IQ
Summary Introduction
To explain: The reason why a phylogenetic tree based on comparison of a single gene could result in an inaccurate hypothesis.
Introduction:Amborella is a monotypic genus of small trees endemic to the Grande Terre of New Caledonia. Amborella is of great interest for plant systematists. This is because molecular phylogenetic analysis consistently places it as the sister group to all other flowering plants.
