They are visiting a Geneticist, a doctor who specialized in genetics
|
|
|
|
| | |
| We are getting DNA tests to see if we are related | |
| | |
|
|
| | |
| The test will use gel electrophoresis to make a DNA fingerprint | |
| | |
|
|
|
|
They learn how a DNA fingerprint can help them
|
|
|
|
| | |
| A DNA fingerprint shows if two individuals have similar STR or short tandem repeats in the DNA | |
| | |
|
|
| | |
| People who are related have similar STR patterns which show up as dark bands on a DNA fingerprint | |
