Bias in DNA profiling

What term is used to describe the graphs that represent DNA profiles?

• Genographs

• Allelograms

• Peakcharts

• Electropherograms

What are the peaks on the DNA profile graphs called?

• Fragments

• Signals

• Alleles

• Markers

What does a DNA profile ultimately distill down to?

• A list of DNA fragments

• A graph of peaks

• A sequence of genes

• A table of alleles

What phenomenon can lead to subjective interpretation of DNA profiles?

• Examiner bias

• Sample contamination

• Genetic similarity

• Analysis paralysis

What is the proposed solution to eliminate examiner bias?

• More training

• Peer review

• Automated analysis

• Blind testing

What is a 'blob' in the context of DNA profiling?

• A technical artifact

• A rare allele

• A peak of interest

• A contamination indicator

What does 'OL allele' stand for?

• Original locus allele

• Off-ladder allele

• Overloaded allele

• Observed length allele

Why do some oppose blind testing in DNA profiling?

• It limits access to information

• It requires more time

• It's less accurate

• It's too expensive

What does the speaker compare giving the answer key before a test to?

• Studying

• Cheating

• Objective analysis

• Blind testing

What is the main benefit of adopting blind testing according to the speaker?

• Faster results

• More objective and scientific outcomes

• Cheaper testing methods

• Easier interpretation of results
