What is the difference between cloning and expression vectors?
Cloning vectors are used to increase the number of copies of the cloned gene or to amplify a foreign gene. Expression vectors are used to increase the expression of the foreign gene product.

How does reproductive isolation increase isolation?

Why does geograpical isolation increase differences between gene pools?
Because they produce with whomever they want which gives them more varieties in a gene pool

How can a proto oncogene be converted into an oncogene without a change or mutation in its coding sequence?
It could happen in three main manners: 1) the formation of multiple copies of the gene (duplications) that increase the expression of the gene 2) the mutation happens in the promoter of the gene or in others non coding regions causing an increase in the level of the mRNA of the gene 3) it could happen a translocation that put the gene under an active promoter (bcl2 in lymphomas) , or brings to the formation of a chimaeric gene (the philadelphia chromosome in leukemia)
How does natural slection affect the allele frequency in a gene pool?
It changes it by, generally, selecting out some alleles thus allowing other alleles to increase their numbers in the populations gene pool.
