Question 1
A forensic scientist has been called to analyse evidence
from a murder scene. She takes a sample of blood from the victim, from a
blood stain on the victims clothes presumed to come from the murderer, and
from two suspects supplied by the Gardaí. She isolates DNA and determines
the pattern using a single locus probe. Examining the resulting gel below,
what do think her conclusion should be?
1 and 5 = victim, 2 = suspect 1, 3 = suspect 2, 4 = size markers, 6 =
blood stain
