DNA 06: Match probabilities assuming population subdivision
A blood stain was recovered from a crime scene and a suspect was later arrested.
The DNA profiles of the crime stain and suspect are C = 10/10 and S = 10/10 at locus D16 and C = 11/13 and S = 11/13 at locus D8.
Assume the corrected allele probabilities:
p(D16/10) = 0.063
p(D8/11) = 0.069 and p(D8/13) = 0.333
Calculate the match probabilities and likelihood ratio assuming that the degree of population subdivision, θ = 0.02.
HP: The suspect left the stain
HD: A random person left the stain
