So far we have discussed reassortment and recombination of alleles. Now we discuss allele conversion by mutation.
Mutation is change in DNA sequence that is inherited by offspring.
A mutation event is how the allele sequence changes. A population of descendents of the individual in which the original mutation event occurred. The mutation is now inherited by the regular reassortment and recombination mechansisms, as are other alleles. In practice, this is hard to measure. This is easy to measure.
