How do rates of mutation "power" molecular clocks?

Answers

Answer 1

Answer: Molecular clocks use rates of mutation to measure evolutionary time.Mutations add up at a fairly constant rate in the DNA of species that evolved from a common ancestor. The more mutations that happened in each lineage, the greater is the differences between these lineages.

Which type of selection leads to increased phenotypic and genetic variation? directional selection disruptive selection stabilizing selection species selection

Answers

The circumstance that concludes whether the organism will be able to accommodate and endure in the changed conditions is called selection.

The correct answer is:

Option B. Disruptive selection.

This can be explained by:

Disruptive or diversifying adaptation occurs when there is a change in population genetics in which the traits are valued over intermediates.

This type of assortment supports either the dominant or the recessive trait but do not favour intermediates.

For example, in selection between tall, short or intermediate organisms the tall and short will be selected over the medium heightened organism.

Therefore, disruptive selection will lead to increased phenotypic and genetic variation.
