Determining relatedness between species

Question 1

Relationship between species

What is a phylogenetic tree or caladogram used for

Answer 1

To describe and depict this evolutionary relationship between species.

Question 2

Relationship between species

What is a molecular homology used for

Answer 2

As evidence, Determine how similar the dna base sequence and amino acid sequences of corresponding protein are between two species.

Question 3

Relationship between species

What is a caladogram (or phylogenetic)

Answer 3

Is taking characteristics that are shared by organisms and then putting together a hypothesis of how you think they may be related.

Question 4

Relationship between species

DNA
Explain the logic behind molecular homology

Answer 4

The greater the amount of time elapsed since the two populations last experience gene flow, the greater number of different mutation acquired in each population and therefore the greater the difference in the base sequence of the same gene in each population.
