The resulting N+1 aneupeloid gamete contains an extra chromosome
When a nucleus divides by mitosis, all of the information from the nuclear
chromosomes is passed on to the daughter cells.
Mitosis is a cell division process that results in the formation of two daughter cells during growth processes and in the replacement of worn-out tissues in the body.
The cells produced must have all the information as the cells replicated
have specialized functions which must be passed from parent cells to the daughter cells.

Generally speaking, there are 2 major forces that cause genetic divergence in the majority of populations and systems.
And those are;
Natural Selection
and
Mutation
Natural selection causes a divergence due to the fact that organisms with " "better", more advantageous traits dependent on their environment, survive and reproduce, while the others have the lesser chance. (This causes traits in the population to change over time.)
Mutilation/Mutations, on the other hand, is a change in the genetic material of an organism-specifically when DNA is copied incorrectly.
This changes a portion of the genetic makeup of an organism, therefore changing the organism, and changing its future generations of offspring (when made...etc)
