If an exogene is introduced into the diploid cell and if it is integrated into the chromosome does it integrate in both chromosomes or in single chromosome?

Dear Rimo,

One way to approach the question is to write down what would need to happen under both possible integration events and then consider if the diploid cell has the capability to do what is needed. Which process would involve the fewest novel capabilities.

Jim Tokuhisa

Intergration of exogenes into a cell is a rare event on the order of one in a thousand cells, so it is unlikely that both chromosomes of a chromosome pair would acquire the introduced gene.
