BIO 301D Lecture Notes - Lecture 4: Tandem Repeat, Genetic Testing, Chromosome
Document Summary
Most informative, meaning it has the lowest coincidental match possibility. (1 in a million or lower) (rmp for random match possibility or coincidental match possibility) Downside dna quality must be good not degraded: mitochondrial dna (more dna then in the chromosome) Mom and all her birds have same mitochondrial dna. But, works on degraded dna samples: y-str. But, can be used to determine the number of males in a sample: dna is good as a forensic tool because: It has a low rmp: dna is easily left behind in usable amounts, dna is moderately stable, methods are now routine (automated) It has all-or-none properties: how might dna typing go wrong, can easily be used to frame someone. Blind how much replication depends on the goal and on the population variation human subjects, human observers of subjective. Knowns (proficiency tests) better equipment things virtually always when choosing things always when greater accuracy is desired.
