Quizplus · Accepted Answer

Tracing a paternal line of inheritance involves analyzing DNA from the Y chromosome, which is only passed down from fathers to their sons. The most commonly used method for this is by analyzing short tandem repeats (STRs) on the Y chromosome. This allows for the creation of a Y chromosome haplotype, which can then be compared to samples from other individuals to determine potential relationships. Sequencing the entire Y chromosome or multiple coding regions on different autosomes would not be necessary for this specific purpose, and analyzing STRs on multiple autosomes would not be as helpful in tracing a paternal line.
