Meiosis involves crossing over where chromosomes exchange genetic segments, resulting in different sets of chromosomes. Each time an egg or sperm created, it is different due to this recombination. Mitosis on the other hand is non-sex cells replicating exact copies of themselves which lead to no genetic variation as they aren't involved in producing offspring.

In order to reproduce, an organism must make a copy of this material, which is passed on to its offspring. Some single-celled organisms reproduce by a process called In binary fission, material from one cell separates into two cells.
Information:Symbiotic relationships are important because they are a major driving force of evolution. This networking and cooperation among species allows them to survive better than they would as individuals.
