If the copying of DNA during sexual reproduction is not accurate, what will be the consequences?

The DNA copying which is not perfectly accurate in the reproduction process results in variations in populations for the survival of species. If the variation are more drastic then the DNA will not be able to function properly leading to the death of the cell.

Name the following: The types of asexual reproduction seen in Planaria.

Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of genes of their single parent. Asexual freshwater planarians reproduce by tearing themselves into two pieces by a process called binary fission. The resulting head and tailpieces regenerate within about a week, forming two new worms.

Name the following: An organism that reproduces by Fragmentation.

Fragmentation is the breaking of the body into parts and then the organism develops all the parts of the body. Fragmentation is the type of reproduction in lower organisms. The fragments which are produced can develop into new organisms. Fragmentation as a method of reproduction is seen in organisms such as filamentous cyanobacteria, moulds, lichens, sponges, flatworms, some annelid worms and sea stars.
