Question

In california, a lack of genetic variation in the argentine ant has allowed the species to spread widely; due to their being so genetically similar to one another, the ants consider all their fellows to be a close relative and thus do not engage in the kind of fierce intercolony struggles that limits the spread of this species in its native argentina.

Answer 1

All variations in a species do not have equal chances of survival. Some of the variations may be so drastic that the new DNA copy cannot work with the cellular apparatus it inherits. ... In asexual reproduction, there is minimum variation that is due to small errors in DNA copy.
