An important application of DNA fingerprinting is relationship testing. Persons who are related genetically have some bands or peaks in common. The number they share depends on the closeness of their genetic relationship. For example, an offspring is expected to receive half of his or her minisatellites from one parent and the rest from the other. The diagram shown here schematically illustrates traditional DNA fingerprints of an offspring, mother, and two potential fathers. In paternity testing, the offspring’s DNA fingerprint is first compared with that of the mother. The bands that the offspring have in common with the mother are depicted in purple. The bands that are not similar between the offspring and the mother must have been inherited from the father. These bands are depicted in red. Which male could be the father?
Regarding the analysis of single marker STR results used in forensic science. Tick all the correct statements:
if a suspect's alleles are identical to those collected at a crime scene, then the suspect is possibly guilty
dizygotic twins can have similar alleles at an STR locus
no correct statement
if a suspect's alleles are different from those found at a crime scene, then the suspect is definitely innocent
monozygotic twins may have different alleles at an STR locus
☐if a suspect's alleles are different from those collected at a crime scene, then the suspect is possibly innocent
☐two unrelated individuals could have a similar genetic profile
monozygotic twins cannot have different alleles at an STR locus
dizygotic twins cannot have similar alleles at an STR locus
☐if a suspect's alleles are identical to those collected at a crime scene, then the suspect is definitely guilty
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

- Suppose you are arrested for a serious crime and a DNA profile is created and entered into databases. Later, you are proven innocent. Should you have the right to have your DNA profile removed from all databases?arrow_forwardA wealthy elderly couple die together in an accident. Soon, a man shows up to claim their fortune, saying that he is their only son who ran away from home as a boy. Other relatives dispute his claim. Hospital records show that the deceased couple were type AB and0 respectively. The claimant to the fortune was type O. Could he be their son? Explain your answer. Two parents think their baby was switched at the hospital. It's 1968, so DNA fingerprinting technology does not exist yet. The mother has blood type A, the father has blood type AB, and the baby has blood type "B." 66 Mother's genotype(s): Draw a Punnett square showing all possible genotypes for children produced by this couple Father's genotype(s): Baby's genotype(s): What is the probability that the baby was switched?arrow_forwardDescribe the mutation that created the Hbs allele: type of mutation, location of mutation on HbA sequence (#of bases from beginning of sequence), nucleotide change (from which base to which base?)
