... Answer: These results can be explained by gene conversion. The gene conversion took place in a limited region of the chromosome (within the pdx-1 gene), but it did not affect the flanking genes (pyr-1 and col-4) located on either side of the pdx-1 gene. In the asci containing two pdx-1 alleles and s ...

Point mutation
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
