Answer #1

Answer

Neutral theory : Most of the genetic mutations are neutral with respect to each other.
Deleterious mutations quickly eliminated and advantageous mutations are extremely rare
Most of the observed variations is selectively neutral and drift predominates when S<1/ (2N).
In neutral theory most of the mutations are deleterious, but they hold why because these will removed by process of natural selection and also they do not make significant contributions to change within or between the species at the molecular level.

Hope it will helpful to you. Thank you

6. (Answer this question using the neutral theory of molecular evolution) One of Charles Darwin's main ideas was that life evolves by natural selection, following a rule of "survival of the fittest." For example, if you look historically at giraffes, it is hypothesized that those with taller necks tended to be selected for evolutionarily because they could reach more food high up in trees. When we consider DNA, the same principles of natural selection apply. Those DNA regions that have...

Intelligent design theory is an argument used by some people to challenge the teaching of evolution in public schools. One of the supporters of this idea claims that certain biological structures, such as the bacterial flagellum, require so many complex parts working together in perfect synchronization that it is not possible that they could have evolved from simpler structures. This argument states that a simpler structure could not perform the same function, which is evidence of “irreducible complexity.” This is...
