Question

7) Motoo Kimura's Neutral theory of molecular evolution states what? Was he right? Explain.

Answer 1

Dans: Motoo Kimura's Neutral theory of molecular evolution : The neutral theory of evolution states that most of the variation within and between species, most evolutionary changes at the molecular devel, are due to random genetic drift of mutant alleles that are selectively neutral. The neutral theory allows for the possibility that most mutations are deleterious, but holds that because these are rapidly removed by natural selection, they do not make good contributions to variation within and between Species at molecular devel

Jt allows for applies only for evolution, le at the molecular level, and is compatib with phenotypic evolution being shaped ay natural selection as said by charles Darwin ay This neutral mutation does not affect an ólga nisms ability to survive a no re produce at Be cause only a fraction of gamets, are Sampledo in each generation of a Species, the theory states that a Mutant allele can arise within a population and reach fixation by chance, rather than by selective advantage. *p Jhis theory got a controversy over the 'interpretation of patterns of molecular divergence and polymorphosim : - Many Stalistical methods for testing this I theory and many resulted 'that it should be detection of selection": 7 In some aspects he is right but in many aspects he was wrong.
