What is the potential consequence of technical problems with poor quality or low amounts of DNA in forensic DNA profiling?
False inclusion of individuals
DNA profiling can only be used to identify people if an existing sample of cells or DNA profile is available.
True
DNA profiling has been instrumental in establishing the innocence of those suspected or previously convicted of a crime.
True
Complete proof of identity or relatedness is possible through DNA profiling.
False
If two DNA profiles are different, they cannot have come from the same person.
True
The probability of a DNA profile coming about by chance is provided when two profiles match.
True
Monozygotic twins share 100% of their alleles.
True
Some alleles are more common in certain populations or ethnic backgrounds, leading to potential false exclusions in DNA profiling.
True
Relatives are less likely to share alleles, with siblings sharing an average of 50%.
True
Familial matching can be used in forensic applications of DNA profiling to identify potential suspects.
True
DNA profiling can be used to determine the source of poached wildlife.
True
DNA profiling can be used to identify people if an ______ sample of cells or DNA profile is available.
existing
Relatives more likely to share alleles. Monozygotic twins – 100%, Parent/Child – 50%, Siblings: 40-60% (Average 50%)
siblings
If two DNA profiles match, it can’t be concluded they came from the same person. Instead, a ______ is provided that the DNA profile in question came about by chance.
