... Any change in the DNA sequence within the gene is a mutation and produces a new allele and a mutant genotype and that could affect the phenoptype. If the mutant allele causes a decrease in gene function it is said to be a loss of function allele. Maybe the allele only works 50% as well as wild-type, ...

... This is believed to happen by gene conversion, as described above for yeast mating types. There are regions of homology upstream and downstream from each VSG gene, that initiate the gene conversion process. The upstream region of homology includes a few copies of a 70bp repeat.
