In forensic casework on sexual assault evidence, what is the advantage of using male-specific amplification?
In forensic casework on sexual assault evidence, what is the advantage of using male-specific amplification?
- It leads to a higher power of discrimination due to genetic shuffling with recombination
- It allows for the generation of rare random match probabilities using the product rule
- Lower levels of male perpetrator DNA can be recovered due to concern about heterozygote allele loss
- It can potentially recover results with lower levels of male perpetrator DNA without concern about heterozygote allele loss (correct)
Why is Y-specific DNA useful in deficiency paternity cases?
Why is Y-specific DNA useful in deficiency paternity cases?
- It provides a higher power of discrimination due to genetic shuffling with recombination
- It allows for the determination of the number of male contributors quickly
- It has a fairly high mutation rate similar to autosomes
- It can be used to tie male children to fathers in motherless paternity cases (correct)
What is a disadvantage of Y-specific DNA in forensic kits with Y STR markers?
What is a disadvantage of Y-specific DNA in forensic kits with Y STR markers?
- It allows for the determination of the number of male contributors quickly
- Loci are independent of one another, allowing for rare random match probabilities
- It cannot generate rare random match probabilities using the product rule (correct)
- It provides a higher power of discrimination due to genetic shuffling with recombination
