Some flat worms reproduce through fragmentation what is a disadvantage of this method

Answer 1

One disadvantage of reproduction through fragmentation in flatworms is the lack of genetic diversity. As the organism is splitting and producing new individuals from its own body parts, there is no mixing of genetic material with other individuals. This results in the offspring being genetically identical or very similar to the parent. A lack of genetic diversity can make a population more susceptible to diseases, changes in the environment, and other selective pressures, as they may not have the necessary genetic variations to adapt and survive.
