Question 1

what is DNA polymorphism?

Answer 1

sequences differences - serves as DNA markers

Question 2

what are the three types of genetic variants?

Answer 2

SNP - single nuc
DIP deletion insertion
SSR simple sequence repear

Question 3

what can SNP let you do in relation to ancestry?

Answer 3

trace it since you share more with closer relatives

Question 4

what can DIPS lead to?

Answer 4

frame shift mutations within exons

Question 5

what is PCR? what can you make?

Answer 5

a way to isolate a fragment of DNA for anaylsis
-primers (1 in 3 to 5 and the other 5 to 3 convert the parent to complementary and convert that )

Question 6

if your given a cahrt with the locus, genotype, and match probaility with the amount of people in the population how can you solve this?

Answer 6

To tell how many have the same profiles multiply all of the match probabilities into decimals and multiply it to how ever many people there are

Question 7

What happens when the oligonucleotides is not an exact match?

Answer 7

then hybridization is less stable making it easier to denature at a lower temperature

Question 8

allele-specific oligonucleotides (ASOS)

Answer 8

only hybridize to one of the two alleles at a SNP location

Question 9

SNP pedigrees can tell you ? and the one weird kid?

Answer 9

which letter causes the issue
- happened because of crossing over
