Interpretation of Single Source DNA Profile Flashcards
1
Q
What can reduce the statistics associated with full 17 loci matches?
A
- mixtures
- incomplete profiles
- relatives
2
Q
What is the question that we ask in relation to the statistics of a DNA profile?
A
What is the chance that a randomly chosen unrelated person would have the same DNA profile that we are seeing in the evidence sample?
3
Q
What are the assumptions to the Product Rule?
A
- alleles need to be independent within the locus and across the loci
- alleles present in the DNA profile are sampled randomly from the population gene pool
