Polymorphic Markers
Pregunta 2
Pregunta
How is the tracing of inheritence phenotypes done?
Respuesta
-
Genetic markers i.e. SNP's
-
Allele complimentation

Pregunta 4
Pregunta
How are physical maps made?
Respuesta
-
Design markers that overlap along the genome
-
Orientation of homologous chromosomes
-
Allele studies
Pregunta 5
Pregunta
Physical maps must be made of physically isolated parts of the genome
Respuesta
- True
- False
Pregunta 6
Pregunta
A genetic marker acts as a reference point in a linkage study
Respuesta
- True
- False
Pregunta 7
Pregunta
Genes are usually used as markers in non-human studies. Why can they not be used in humans?
Respuesta
-
Human genes are more unstable
-
Human genes vary too much
-
Human genes are more highly conserved
Pregunta 8
Pregunta
What is the preferred form of marker in humans?
Respuesta
-
Polymorphic introns
-
Polymorphic Exons
-
SNP's
Pregunta 9
Pregunta
More polymorphic DNA= less useful
Respuesta
- True
- False
Pregunta 10
Pregunta
Homozygotes are more useful in genetic mapping than heterozygotes
Respuesta
- True
- False
Pregunta 11
Pregunta
How must markers be placed along the chromosome?
Respuesta
-
Evenly spaced
-
As lightly as possibly
-
As densely as possible
Pregunta 12
Pregunta
The aim it to combine genetic and physical maps
Respuesta
- True
- False
Pregunta 13
Pregunta
Once you have a marker with a high linkage to a disease/trait, how do you use the physical map?
Respuesta
-
Find the marker and look for genes very close to it
-
Find the suspect gene and look for markers very close to it
-
Find the marker and look for genes as far away as possible
