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 are examples of neutral mutations?
For example, bovine and human insulin, while differing in amino acid sequence are still able to perform the same function. The amino acid substitutions between species were seen therefore to be neutral or not impactful to the function of the protein.
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.
Is eye color a neutral mutation?
Nature shuffles our genes The mutation of brown eyes to blue represents neither a positive nor a negative mutation. It is one of several mutations such as hair colour, baldness, freckles and beauty spots, which neither increases nor reduces a human’s chance of survival.
What is a neutral effect?
Neutral effect means that the cumulative effects of an alternative are expected to be no different than they had been under past, present, and reasonably foreseeable future actions.
What nationality has gray eyes?
