Today i was looking at other forms of DNA analysis other than Short tandem repeats (STR) which is used for DNA fingerprinting in crime labs I found one less commonly called Restriction Fragment Length Polymorphism (RFLP) which works very similar to STR they just look at different things which makes me wonder why they dont use RFLP so much after further research i found out that RFLP requires a sample about the size of a quarter and is about 50% efective and STR is 90% efective with a stain the size of a pinhead so i see why RFLP isnt used anymore Short Tandem Repeats which we perfomed in Chicago is much more effective
