Detailed explanation-1: -If you have to make more than one cut to separate a group of organisms from the rest of the tree, that group does not form a clade. Such non-clade groups are called either polyphyletic or paraphyletic groups depending on which taxa they include.

Detailed explanation-2: -Just like there are different types of families, there are different types of clades. The three major types are: monophyletic, paraphyletic and polyphyletic. Monophyletic refers to just one clade; meaning these terms are interchangeable.

Detailed explanation-3: -Monophyletic: monophyletic clades means a group of organisms with a single clade in it. Here you will find only one ancestor for many descendants. Paraphyletic: this clade includes an ancestor and multiple descendants, removing some 2-3 groups. Polyphyletic: in this clade, organisms possess homoplasy traits.

Detailed explanation-4: -A monophyletic group, sometimes called a clade, includes an ancestral taxon and all of its descendants.
