Questão 7
Questão
Genes are usually used as markers in non-human studies. Why can they not be used in humans?
Responda
-
Human genes are more unstable
-
Human genes vary too much
-
Human genes are more highly conserved

Responda
-
Polymorphic introns
-
Polymorphic Exons
-
SNP's
Questão 9
Questão
More polymorphic DNA= less useful
Responda
- True
- False
Questão 10
Questão
Homozygotes are more useful in genetic mapping than heterozygotes
Responda
- True
- False
Questão 11
Questão
How must markers be placed along the chromosome?
Responda
-
Evenly spaced
-
As lightly as possibly
-
As densely as possible
Questão 12
Questão
The aim it to combine genetic and physical maps
Responda
- True
- False
Questão 13
Questão
Once you have a marker with a high linkage to a disease/trait, how do you use the physical map?
Responda
-
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
