multicopy gene family evolution on primate y chromosomes

... Contrary to previous theories, the Y chromosome is an important determinant of male phenotype [15–17]. The Y chromosome has been found to be associated with male fertility in humans [18] and even less obvious traits like lifespan [19] and locomotive activity [20] in Drosophila species. Therefore, an ...

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.
