"Describe the web and ring models and how they differ from the phylogenetic tree." Flashcards
What is a phylogenetic tree?
A phylogenetic tree is a diagram that represents the evolutionary relationships among various biological species based on their genetic characteristics.
True or False: The web model represents a linear evolutionary path.
False
Fill in the blank: The ______ model emphasizes the interconnectedness of species through horizontal gene transfer.
web
What distinguishes the ring model from the traditional phylogenetic tree?
The ring model illustrates a circular representation of evolutionary relationships, allowing for the inclusion of reticulate evolution.
Multiple Choice: Which model incorporates horizontal gene transfer? A) Phylogenetic tree B) Web model C) Ring model D) Both B and C
D) Both B and C
What is a key characteristic of the ring model?
The ring model shows that species can have multiple ancestors and can merge or diverge in a circular format.
True or False: The phylogenetic tree can accurately represent all evolutionary relationships.
False
What does the web model highlight about species evolution?
The web model highlights that evolution is not a simple tree structure but involves complex interconnections and gene exchanges among species.
Fill in the blank: The ______ model is useful for depicting species that have shared traits due to horizontal gene transfer.
web
How do the web and ring models differ from the phylogenetic tree in terms of evolutionary representation?
The web and ring models account for complex interactions like horizontal gene transfer and reticulate evolution, while the phylogenetic tree typically represents linear, branching evolution.
