Genetic fingerprints are used to establish genetic relationships and assess population variability by comparing DNA fragment patterns.
Genetic fingerprints are used to determine genetic relationships by comparing inherited sequences, with more matching bands indicating closer relation. They also help assess genetic variability within a population, where more non-matching bands suggest greater genetic difference.
| Front | Uses of genetic fingerprints |
|---|---|
| Back | Determining genetic relationships- we inherit VNTR base sequences from parents, the more bands that match on a genetic fingerprint the more closely related two people are. Can be used in paternity test to determine the biological father of a child Determining genetic variability within a population- the greater number of bands that don't match on a genetic fingerprint the more genetically different people are. You can compare the number of repeats at several places in the genome for a population to find out how genetically varied that population is. |
