Phylogenetic Trees
Biology ⇒ Evolution and Diversity
Phylogenetic Trees starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Phylogenetic Trees.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A phylogenetic tree shows that species A and B share a more recent common ancestor with each other than with species C. What does this imply about their evolutionary relationship?
A scientist is comparing DNA sequences of four species to construct a phylogenetic tree. What type of data is she using?
Describe the difference between homologous and analogous traits in the context of phylogenetic trees.
Describe the difference between rooted and unrooted phylogenetic trees.
Describe what is meant by a 'basal taxon' in a phylogenetic tree.
Explain the importance of using multiple genes or traits when constructing a phylogenetic tree.
Explain why convergent evolution can complicate the construction of phylogenetic trees.
Explain why phylogenetic trees are considered hypotheses.
What is a phylogenetic tree?
