1What does genetic mapping rely on?
- AInheritence phenotypes
- BPolymorphic Markers
2How is the tracing of inheritence phenotypes done?
- AGenetic markers i.e. SNP's
- BAllele complimentation
- CMeiotic Tests
31cM =
- A1% recombination
- B10% recombination
- C1kB
- D10kB
4How are physical maps made?
- ADesign markers that overlap along the genome
- BOrientation of homologous chromosomes
- CAllele studies
5Physical maps must be made of physically isolated parts of the genome
- AVerdadero
- BFalso
6A genetic marker acts as a reference point in a linkage study
- AVerdadero
- BFalso
7Genes are usually used as markers in non-human studies. Why can they not be used in humans?
- AHuman genes are more unstable
- BHuman genes vary too much
- CHuman genes are more highly conserved
8What is the preferred form of marker in humans?
- APolymorphic introns
- BPolymorphic Exons
- CSNP's
9More polymorphic DNA= less useful
- AVerdadero
- BFalso
10Homozygotes are more useful in genetic mapping than heterozygotes
- AVerdadero
- BFalso
11How must markers be placed along the chromosome?
- AEvenly spaced
- BAs lightly as possibly
- CAs densely as possible
12The aim it to combine genetic and physical maps
- AVerdadero
- BFalso
13Once you have a marker with a high linkage to a disease/trait, how do you use the physical map?
- AFind the marker and look for genes very close to it
- BFind the suspect gene and look for markers very close to it
- CFind the marker and look for genes as far away as possible
14Which of the following are evenly distributed?
- ASNP's
- BMinisatellites
- CMicrosatellites
- DRFLP's
15Microsatellites are highly polymorphic
- AVerdadero
- BFalso
16Which of the following are most useful as markers?
- ARFLP's
- BMinisatellites
- CMicrosetellites
- DSNP's
17There are two alleles (usually) for RFLP's
- AVerdadero
- BFalso
18How are minisatellites typed?
- ASouthern Hybridisation
- BGel Electrophoresis
- CPCR
19There are more than 10^10 SNP's in the human genome
- AVerdadero
- BFalso
