Because scientists find new information all the time, and this sometimes contradicts what we thought we knew. Of course we want to be as right as we can be at any given time, so the trees are revised based on the newfound facts.
No, because they do not identify individuals.
both cladograms and phylogenic trees
The three types of cladograms are rooted cladograms, unrooted cladograms, and strict consensus cladograms. Rooted cladograms include a common ancestor at the root, unrooted cladograms lack this feature, and strict consensus cladograms display only relationships supported by all data.
It is a polygenic character
POLYGENIC!
Traits that are produced by the interaction of several genes are called polygenic traits. Examples of polygenic traits are height and skin color.
Polygenic Traits
Derived Characters Synapomorphies
Cladistics is a method in biology that groups organisms based on shared characteristics derived from a common ancestor. This approach helps to understand evolutionary relationships among species by analyzing their shared traits and constructing evolutionary trees or cladograms. By focusing on shared derived characteristics, cladistics aims to identify and classify organisms based on their evolutionary history.
false, height is a polygenic trait
two or more genes
Polygenic genes are usually dominant genes.
