7. A burned body is found after a warehouse fire. You cannot obtain nuclear DNA suitable for testing, but you are able to obtain a sample of the person's mtDNA. What challenge will you encounter when trying to identify the person using mtDNA? Everyone has the same mtDNA so you won't be able to narrow identity down. mtDNA is most useful for information on traits like hair color so it won't narrow things down much. mtDNA only shows patrilineal lineage so it will only show the father's mtDNA. mtDNA is time consuming and expensive; not all labs have the capabilities to test this.

Genetic Variation

Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.

Quantitative Genetics

Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
