Expert Evidence: Case Studies Part 8

The transcript discusses the concept of likelihood ratio in DNA profiling, emphasizing its significance in determining the probability of a DNA profile originating from specific individuals compared to random individuals from the Australian population. It highlights a case involving Maxwell Hart and John Smith, explaining that the DNA profile is 900 million times more likely to occur from their biological material than from a random pairing. The transcript underscores the importance of using population sample data to calculate these probabilities accurately.

What is the minimum value of the likelihood ratio mentioned in the video?

• 900 million

• 900 thousand

• 90 million

• 9 million

According to the video, the DNA profile is how many times more likely to occur from Maxwell Hart and John Smith compared to a random individual?

• 9 billion times

• 900 million times

• 90 million times

• 9 million times

What population sample data is used to estimate the likelihood ratio?

• Australian African population

• Australian Caucasian population

• Australian Asian population

• Australian Aboriginal population

In the context of the video, what does a likelihood ratio of 900 million imply?

• The DNA profile is equally likely to occur from any individual.

• The DNA profile is 900 million times more likely to occur from the specified individuals.

• The DNA profile is 900 million times less likely to occur from the specified individuals.

• The DNA profile is 900 million times more likely to occur from a random individual.

What is the probability mentioned in the video regarding the likelihood ratio?

• 85%

• 99%

• 90%

• 95%
