some flat worms reproduce through fragmentation. What is the disadvantage of this method?
1 answer
The disadvantage of reproduction through fragmentation in flatworms is the lack of genetic diversity. Fragmentation involves breaking the body of the flatworm into multiple pieces, each of which can grow into a new individual. Since the offspring are genetically identical to the parent, it limits genetic variation within the population. This lack of genetic diversity can be detrimental in adaptation to changing environmental conditions, resistance against diseases, and the overall survival of the species.
