Final Answer:
The main goal(s) for obtaining and testing DNA include determining ancestry, identifying genetic disorders, and establishing paternity, so the correct answer is (d) All of the above.
a) Determining ancestry
b) Identifying genetic disorders
c) Establishing paternity
Step-by-step explanation:
Obtaining and testing DNA serve various purposes, and the three options—determining ancestry, identifying genetic disorders, and establishing paternity—encompass the primary goals of DNA analysis. Firstly, DNA testing for ancestry involves examining specific genetic markers to trace an individual's familial and geographic origins. This has gained popularity through services like DNA ancestry testing kits, providing insights into one's heritage based on genetic similarities with diverse populations.
Secondly, DNA testing plays a crucial role in identifying genetic disorders. By analyzing an individual's DNA, researchers and healthcare professionals can identify specific mutations or variations associated with genetic diseases. This enables early detection, diagnosis, and personalized treatment plans for individuals at risk or affected by genetic disorders.
Lastly, establishing paternity is another important application of DNA testing. By comparing the DNA profiles of a child and a potential father, it is possible to determine biological parentage with high accuracy. This has significant implications in legal contexts, such as child custody cases and inheritance disputes.
In summary, the versatility of DNA analysis allows it to address a range of objectives, from exploring ancestral roots to identifying potential health risks and resolving questions of parentage.
