What is the purpose of paternity testing?
What is the purpose of paternity testing?
- To compare blood groups and DNA profiles to establish paternity (correct)
- To determine the gender of the child
- To analyze the mother's DNA
- To identify the child's blood group
How do blood groups help in indicating possible 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 (correct)
- Child's blood group must match exactly with the father's blood group
- Blood grouping is not as reliable as DNA profiling
- Blood group comparison can definitively confirm paternity
Why is DNA profiling considered more reliable than blood grouping for paternity testing?
Why is DNA profiling considered more reliable than blood grouping for paternity testing?
- DNA profiling examines similarities in nucleotide sequences between father and child (correct)
- DNA profiling compares the mother's and possible father's DNA directly
- Blood grouping does not involve analyzing nucleotide sequences
- Blood grouping only looks at 50% of the child's DNA fragments
