Asexual reproduction
Reproduction by which offspring arise from a single organism and inherited the jeans of that parent only
Sexual reproduction
Reproductive process involving two sexes and resulting in an offspring
Binary fission
The splitting of an organism into two new organisms about the same size
Budding
Asexual reproduction process in which a bud forms on an organism
Spore formation
A haploid cell that can develop into a new organism without fertilization
Fragmentation
Asexual process in which a new small piece of fragment grows into a new individual
Disadvantages to asexual reproduction
If there’s an issue and reproduction of one organism that can wipe out the entire population
Mutations can cause diseases and destroy offsprings
Advantages to a sexual reproduction
No energy required to find a mate
Can reproduce quickly
