Concept explainers
To explain: The possible reasons for two different genes to imply different phylogenetic relationships among a group of species.
Introduction: Inheritance is the basis of evolution. The study of the evolution of descendants from common ancestors is called phylogeny. The diagrammatic representation of phylogeny of an organism is termed as a polygenetic tree.
To explain: The gene that accurately portrays the true history of the formation of these species.
Introduction: Inheritance is the basis of evolution. The study of the evolution of descendants from common ancestors is called phylogeny. Two different genes can imply different phylogenetic relationships among a group of species.
To explain: Whether it is possible for both phylogenetic trees to be accurate even if there has been only one history of species divergence.
