Question: What Is Neutral Variation?

What is the rate of neutral substitution?

The rate of substitutions is calculated as the number of new mutations in each generation (Nu) multiplied by the probability each new mutation reaches fixation (1/N), which equals u.

In other words, for neutral mutations, the rate of substitution is equal to the rate of mutation!.

What is the importance of neutral variation in evolution?

What is the importance of neutral variation in evolution? Neutral variation increases genetic variation, allowing a population to carry more alleles that may help it respond to environmental change. Variations are considered neutral if they are neither advantageous nor deleterious.

Why are mutations neutral?

These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode. Many other mutations have no effect on the organism because they are repaired before protein synthesis occurs.
