What is wrong with simply saying that a suspect is included in a mixture without providing any statistics? Why is it important to establish independence between alleles and between loci?
im assuming allele frequency in dna, particualrily forensics. class is forensic dna analysis.
Since DNA sequences are passed down from one generation to the next, people with closer familial relationship tend to have more of their DNA sequences in common. As a result, people who are more genetically related tend to share some similar patterns in their DNA fingerprinting. If you are comparing samples, which of the following can be determined with DNA fingerprinting?
Group of answer choices? right chances
Which fraternal twin each sample came from
Which identical twin each sample is from
If the samples are from people who are married
If the samples came from mother and child
asap please
Matching DNA samples in forensics uses a specific set of small “genes” called________ . The alleles of these genes in different people vary in the__________ of the allele. The pattern of these alleles that a given person possesses is called his or___________ her .
