Thomas Hunt Morgan, 1933
... One evening in 1913 one of Morgan’s students, Alfred Sturtevant took home some of Morgan’s breeding records. Reasoning that the closer genes are on the chromosome the less likely they are to cross over with the homologous chromosome, he worked all night and the next morning presented Morgan with a ...

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.
