DNA-Based Facial Reconstruction Quiz

What was the outcome of the facial reconstruction case involving Shaquana Caldwell?

• The reconstruction was deemed inaccurate.

• The case was closed without leads.

• Her killer was caught.

• Her identity remained unknown.

Which two methods are combined in facial reconstruction by Parabon?

• Facial recognition software and DNA analysis

• Forensic sculpture and DNA phenotyping

• DNA sequencing and fingerprint analysis

• Forensic anthropology and dental records

What is the main advantage of using DNA over forensic sculpture in facial reconstruction?

• Forensic sculpture is faster.

• DNA provides a more accurate representation.

• DNA is cheaper to analyze.

• Forensic sculpture is more widely accepted.

What is the role of single nucleotide polymorphisms (SNPs) in determining facial features?

• They are the sole determinant of facial features.

• They contribute to the 0.1% of DNA that makes individuals unique.

• They are responsible for all genetic disorders.

• They have no impact on facial features.

What is the significance of the 0.1% of DNA in humans?

• It is identical in all humans.

• It has no known function.

• It is responsible for our unique physical traits.

• It determines our blood type.

Why is it important to have a representative sample in DNA phenotyping?

• To ensure the algorithm works for all ethnic groups.

• To reduce the cost of research.

• To speed up the data collection process.

• To eliminate the need for forensic experts.

What is the purpose of embedding hair in low melt point plastic during analysis?

• To change the color of the hair.

• To make it easier to cut and analyze.

• To remove impurities from the hair.

• To preserve the hair for future use.

What is a major concern regarding the premature deployment of DNA phenotyping technology?

• It is not accepted by the scientific community.

• It requires too much computational power.

• It is too expensive to implement.

• It could lead to incorrect identifications.

How does the environment affect DNA phenotyping predictions?

• It only affects hair color.

• It makes predictions 100% accurate.

• It has no effect on predictions.

• It can alter the expression of certain traits.

What is a limitation of DNA phenotyping in predicting facial features?

• It is always 100% accurate.

• It cannot account for environmental influences.

• It can determine a person's exact age.

• It can predict scars and tattoos.
