21 Questions
What is the purpose of paternity testing?
To compare blood groups and DNA profiles to establish paternity
How do blood groups help in indicating possible paternity?
If mother's and potential father's blood groups cannot produce child's blood group, man is not the father
Why is DNA profiling considered more reliable than blood grouping for paternity testing?
DNA profiling examines similarities in nucleotide sequences between father and child
In paternity testing, what does it mean if 50% of the child's DNA fragments match those of the potential father?
The child inherited exactly half of its DNA from the father
Why can blood grouping be inconclusive in determining paternity?
Many men may share the same blood group
What is the purpose of paternity testing involving DNA profiling?
To analyze nucleotide sequences in the DNA of the father and child
Why can blood grouping alone sometimes be inconclusive in determining paternity?
Many men may share the same blood group
In paternity testing, what does it mean if the child's blood group could not have been produced by those of the mother and potential father?
The man is not the father
How does comparing DNA fragments between a child and a potential father help in paternity testing?
To identify if a child has 50% DNA from each parent
Why is DNA profiling preferred over blood grouping for paternity testing?
DNA profiling provides more reliable evidence for paternity
What aspect of a child's DNA is crucial in confirming paternity when comparing with a potential father?
Nucleotide sequences
Why may two individuals having the same blood group not be genetically related?
Many people have the same blood group
What percentage of DNA fragments should match between a child and a potential father to support the claim of biological paternity?
50%
What can be deduced if the child's blood group could not have been produced by those of the mother and potential father?
The man is not the father
Why is DNA profiling considered more conclusive than blood grouping for paternity testing?
DNA profiling involves comparing nucleotide sequences which are unique to each individual
If 50% of the child's DNA fragments match those of a potential father, what does this suggest?
The man could be the biological father
Why is comparing DNA fragments between a child and a potential father more reliable for paternity testing than comparing blood groups?
Blood groups are less specific than DNA fragments
What limitation of blood grouping for paternity testing is highlighted in the text?
Many individuals may share the same blood group
How does the presence of shared blood groups among unrelated individuals impact paternity testing?
It can lead to inconclusive results in determining paternity
What makes DNA profiling a more preferable method for determining paternity compared to blood grouping?
DNA profiling provides more conclusive evidence based on unique genetic markers
Why can two individuals having the same blood group still not be genetically related according to the text?
Shared blood groups do not determine genetic relationships
