Answer:

The copies generated are similar but not identical because crossing over takes place during the reductional division or meiosis which results in some variation in each gamete produced.

Since this cross over takes place at a single position the rest part of the chromosome remains intact and is same in other gametes produced.

Hence the copies generated ate similar but not exactly identical.

Hope it helps..

DNA copies generated will be similar, but may not be identical to the original as some variations  are so drastic that new DNA copy cannot work with the cellular apparatus it inherits. Such a newborn cell  will simply die. Therefore, there could be many other variations in the DNA copies that would not lead to  such a drastic outcome. Thus, the surviving cells are similar but slightly different from each other. This  tendency of variation during reproduction is the basis for evolution .
