Did you know facts about DNa fingerprinting
- Did you know that the human genome is made up of about 3 billion nucleotides which are 99.9% identical from one person to the next person?
That means that 0.1% is the difference in DNA that makes us different from one another.
- Paternity test compare segments of DNA between the potential father and child
- There are other types of types of relationship tests that can compare DNA between siblings, grandparents, grandchildren, etc.
- DNA tests can help you understand the risk of a disease
- DNA can be stored either as cells on a cotton swab, buccal brush or frozen blood or in extracted form.
- DNA analysis usually looks at 13 specific DNA markers (segments of DNA) in forensics. This is to keep everything constant and the same for each time that its done.
- The odds that two people will have the same 13-loci DNA profile is about one in one billion.
- A DNA fingerprint is a set of DNA markers that is different for each individual except with identical twins.
- Identical twins share about 100% of their genes.
- Siblings share about 50 percent of their genes.
- A parent and child share 50% of their genes.
- DNA is used in wildlife forensics to identify endangered species and people who hunt them, also known as poachers.
- A lot of countries in the world such as the US and UK maintain a DNA database of convicted criminals.
- DNA testing is used to authenticate expensive foods like caviar and fine wine.
