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.

false, height is a polygenic trait
Polygenic genes are usually dominant genes.
two or more genes
To learn to read cladograms effectively, one can start by understanding the basic principles of cladistics, such as shared characteristics and common ancestry. Practice analyzing different cladograms and identifying the relationships between organisms. It is also helpful to study the terminology used in cladistics and seek guidance from textbooks or online resources. With consistent practice and study, one can improve their ability to interpret and understand cladograms.
