... However, the probability matrix is the main tool for deriving a sensible scoring matrix. To find the probability that amino acid a will mutate be replaced by amino acid b at a time t time units later, we need to calculate the a,b-th entry of the matrix Mt.

Finding the wheat homologues of genes from model organisms

As such, the genetic architecture underpinning traits in model species might not be representative of other plant species. This implies that genes found in model species might not be present in wheat and vice versa ...

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.
