Answer:
C.dispersal
Explanation:
The dispersal refers both to the movement of individuals (animals, plants, fungi, bacteria, among others) from birth to the place of reproduction, or to the place of breeding for another species.
Through the simple movement from one habitat to another the dispersion of the individual has consequences not only for a species, but also for population dynamics, genetics, and collective distribution.
In this case, as some females have no assas, we can conclude that these females came from another region, through the dispersal, being belonged to another species.
