Question

Define intraspecies and interspecies genetic diseases. How do these term relate to DNA barcoding?

Answer 1

Intraspecies genetic diseases are the genetic diseases which develops due to intraspecific variation of gene, it takes place in the members of the same species; whereas Interspecies genetic diseases occurs in the individuals of different species.

DNA barcoding applies on a short, standarized region of genome and depends on the variation of that sequence. It is specified as a barcode to identify species accurately. DNA barcoding can be used to detect error in seguences of GenBank by assessing extreme intraspecific and shallow interspecific divergences which can aid in investigating causal taxonomical problems or other errors. A DNA barcode is considered ideal when it provides for greater interspecies variability in comparison to intraspecific and provide for trusted, fast and cost effective identification of species.
