0:00 so one of the things you want to

0:01 consider when you're confronted with

0:03 questions about is the database large

0:06 enough so the other attack that the

0:09 defense will often take with you is say

0:11 well you have this number of 1 and 10

0:12 quadrillion but you only have a database

0:15 of 150 people so how can you go from 150

0:19 people to 1 in 10 quadrillion have you

0:23 heard that one before that's a common

0:25 one well you guys should be able to

0:27 answer that by now right

0:29 150 people are a sample of 300

0:32 chromosomes and the fact that we're

0:34 using markers that have common alleles

0:37 means that a question we're trying to

0:40 answer by collecting these people is do

0:42 we have enough people to score their

0:44 accurately the number of common alleles
