Homework Answers
Answer: Suspect B
may be the culprit
Explanation:
DNA fingerprinting is a diagnostic method to determine the source
of DNA based on DNA polymorphism.
Individuals contain 99.9% identical genomic sequence. However, the
remaining 0.1% of the genome (3 X 10^8 bp) exhibits
polymorphism.
This polymorphism can be SNPs or in-dels or inversions or
duplications.
The crime scene sample is taken as a
reference to identify its origin. From the given image, it is clear
that suspect B exhibits an identical banding pattern to the crime
scene sample.

When there is a match between a forensic DNA sample collected
at a crime scene and DNA subpoenaed from a suspect, the genotype
frequency can be interpreted in two ways. In one sense, it is the
probability of finding that specific genotype in the population. In
another sense it is the probability that the match is due to
chance.

Here is an example using 3 CODIS STR results. DNA evidence was
found at a crime scene. Due to the poor quality of the DNA sample,
only 3 of the 13 CODIS STRs could be determined. The table below
lists the analytical results for the three STRs in the second and
third columns (Allele A and Allele B).
