STR Analysis Can Also Be Used for Crime Scene Investigations

question 42

Multiple Choice

STR analysis can also be used for crime scene investigations in addition to maternity testing.Suppose that the results for the Mom were found at a crime scene,that the daughter's and the son's results were from possible suspects,and that each of the DNA markers in the gel was an STR marker.Would these results be enough to convince a jury that the results from the daughter matched the crime scene DNA (Mom) ?

• A)Yes,because the two STR markers match in size.
• B)Yes,because you need only one STR marker to match to definitely make a connection between two people's DNA.
• C)No,because even though two STR markers matched,there still could be mismatches in the other 11 markers.
• D)No,because blood-typing data analysis was not performed.
