Case
No 6 The Stolen Car
A
car was recovered by police after being stolen for several days.
Detectives found a hat in the car that did not belong to the owner of the
car. DNA typing analysis using D1S80 locus
was performed on full hair strands recovered from the hat. The genotype
from the evidence sample at the D1S80 locus was 23,
26. D1S80
is a VNTR
locus used in forensic DNA typing. It is typed using PCR
method. Police
picked up six suspects and blood samples were taken from them to perform
the DNA analysis. The results are shown in the Figure below. The suspects
are designated as 2, 3, 5, 6, 8, and 9. Questions 1 through 9
are related to the Figure below. (Before you attempt to answer the questions, click on D1S80
and VNTR above to learn about them).
What is the genotype of suspect 2?
What is the
genotype of suspect 3?
What is the
genotype of suspect 5?
What is the
genotype of suspect 6?
What is the
genotype of suspect 8?
What is the
genotype of suspect 9?
Do any of them
matches the evidence sample?
What are the
samples in lanes 1, 4, 7, and 10?
There is a missing
allele in lanes 1, 4, 7, and 10. Which one is it?
