15 Questions
In forensic casework on sexual assault evidence, what is the advantage of using male-specific amplification?
It can potentially recover results with lower levels of male perpetrator DNA without concern about heterozygote allele loss
Why is Y-specific DNA useful in deficiency paternity cases?
It can be used to tie male children to fathers in motherless paternity cases
What is a disadvantage of Y-specific DNA in forensic kits with Y STR markers?
It cannot generate rare random match probabilities using the product rule
Why are family members likely to have indistinguishable haplotypes with Y-specific DNA?
Unless mutations have occurred, leading to 'family' identification
What is the potential benefit of using Y-specific DNA in missing persons investigations?
Patrilineal male relatives may be used for reference samples
In forensic casework on sexual assault evidence, what is a potential advantage of using male-specific amplification?
To determine the number of male contributors quickly
What is a disadvantage of Y-specific DNA in forensic kits with Y STR markers?
Independence of loci, leading to rare random match probabilities
What is the potential benefit of using Y-specific DNA in missing persons investigations?
Ability to tie male children to fathers in motherless paternity cases
Why is Y-specific DNA useful in deficiency paternity cases?
To tie male children to fathers in motherless paternity cases
Why are family members likely to have indistinguishable haplotypes with Y-specific DNA?
Due to the ability to use haplotypes for family identification
In forensic casework on sexual assault evidence, what is a potential disadvantage of using Y-specific DNA?
Lower power of discrimination due to genetic shuffling with recombination
What is a potential drawback of using male-specific amplification in forensic casework on sexual assault evidence?
Concern about heterozygote allele loss via stochastic PCR amplification
Why is Y-specific DNA useful in deficiency paternity cases?
Tying male children to fathers in motherless paternity cases
What is a potential benefit of using Y-specific DNA in missing persons investigations?
Ability to use patrilineal male relatives for reference samples
What is a potential drawback of Y-specific DNA in forensic kits with Y STR markers?
Indistinguishable haplotypes among family members unless mutations have occurred
