Fill in the blank. DNA fingerprinting can be used to identify closely related organisms, analyze samples found at crime scenes using forensic technology, and blank. (A) Create recombinant DNA, (B) determine the biological parents of a child, (C) treat genetic and hereditary diseases, or (D) generate synthetic sections of DNA.

Every person with the exception of identical twins has a unique genome. DNA fingerprinting is a technique used to make a visual representation of a person’s unique genetic makeup. By visualizing and viewing a person’s genetic makeup, we can find some valuable information. For instance, we can compare samples of DNA to determine if a person was present at a crime scene. Or we can compare samples of DNA from different species to investigate evolutionary relationships.

DNA fingerprinting can also be used to settle issues of paternity in the case of a disputed lineage of a child. This is because the child will have inherited half of their genetic material and therefore half their DNA fingerprint from their mother and half from their father. By comparing the DNA fingerprint of a child to that of the potential fathers, scientists can determine whether a male is likely related to a child.

However, DNA fingerprinting is not a way to create any type of genetic material or treat any genetic disease. And we do not use DNA fingerprinting to generate synthetic sections of DNA, but only to analyze a sample of DNA that we have taken. So the correct answer is (B). DNA fingerprinting can be used to identify closely related organisms, analyze samples found at crime scenes using forensic technology, and determine the biological parents of a child.
