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?
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.
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.
