Phylogenetic Trees

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 12
A phylogenetic tree shows that species A and B share a more recent common ancestor with each other than with species C. Which two species are more closely related?
A researcher is constructing a phylogenetic tree using both morphological and molecular data. What is the advantage of using multiple data types?
Describe the difference between a cladogram and a phylogram.
Describe the principle of maximum parsimony in phylogenetic analysis.
Describe what is meant by a 'clade' in a phylogenetic tree.
Describe what is meant by a 'sister group' in a phylogenetic tree.
Explain the difference between a rooted and an unrooted phylogenetic tree.
Explain the difference between homologous and analogous structures in the context of phylogenetic trees.
Explain why convergent evolution can complicate the construction of phylogenetic trees.
Explain why molecular data (such as DNA sequences) are often used to construct phylogenetic trees.
Explain why outgroups are used in phylogenetic analysis.
Given the following DNA sequences for three species:
Species 1: ATCG
Species 2: ATGG
Species 3: TTGG
Which two species are most closely related based on these sequences?
What is a phylogenetic tree?
