Document Summary
L2 dna must be hold up in court as scientific indications. Highly variable = can be greatly differentiated from individuals. Heterozygotes have different alleles at the same locus, and can be resolved from one another* X - # of repeats of the unit. Y freq of allele, number of times its repeated. More alleles and more frequencies, more discriminatory between individuals within a population and across populations. Some sizes can overlap, that"s why dyes are diferent. Products of this gel is based on chromosome 1. Coloured peaks = dna standards (reference) e. g. this person has a genotype 19 and 22. 19 repeats and 22 repeats on the 2 chromosomes. P13 (a) lots of matches at particular locus (b) if compared with database, only work with locus and genotype p14. What is the random match probability = prob that someone else is in that population. P16 hwe is used to analyze dna profiles from cs.
