Q6.
Which of the following is incorrect regarding the terminologies of phylogenetics?

a.

The connecting point where two adjacent branches join is called a node

b.

Node represents an inferred ancestor of extant taxa

c.

At the tips of the branches are long lost species or sequences

d.

The lines in the tree are called branches

Discuss
Answer: (c).At the tips of the branches are long lost species or sequences
Q7.
Which of the following is incorrect regarding the terminologies of phylogenetics?

a.

A group of taxa descended from a single common ancestor is defined as a clade or monophyletic group

b.

In a monophyletic group, two taxa share a unique common ancestor shared by other taxa as well

c.

Lineage is often synonymous with a tree branch leading to a defined monophyletic group

d.

When a number of taxa share more than one closest common ancestors, they do not fit the definition of a clade. In this case, they are referred to as paraphyletic

Discuss
Answer: (b).In a monophyletic group, two taxa share a unique common ancestor shared by other taxa as well
Q8.
Which of the following is incorrect regarding the terminologies of phylogenetics?

a.

The branching pattern in a tree is called tree topology

b.

In case of dichotomy, each ancestor divides and gives rise to multiple descendants

d.

An unrooted phylogenetic tree does not assume knowledge of a common ancestor

Discuss
Answer: (c).In case of dichotomy, each ancestor divides and gives rise to multiple descendants
