Which Type of Reproduction is Better: Asexual or Sexual Reproduction? “Nature has invented reproduction as a mechanism for life to move forward. As a life force that passes right through us and makes us alike in the evolution of life”(Louis Schwartzberg). Across the Earth, the main reason why cell division is so that organism can make more copies of the cells. Reproduction is the process of making offspring that are able to survive in the environment they are born into. There are two major forms of reproduction, which are asexual reproduction and sexual reproduction. Sexual reproduction is the production of new living organism by combining genetic information from two individuals of different sexes (an egg and sperm cell), while asexual reproduction is the production without the fusion of sex cells or gametes. According to The Christian Science Monitor, about 85 percent of living things, mostly multi celled and complex organism, reproduce sexually, whereas the rest, generally bacteria or single celled organisms, reproduce asexually. The aim is to figure out which types of reproduction are better to adapt and survive the changing environment. Even though these two types of reproduction have some similarities in common, there are also a variety of differences in theses types of reproduction, which are how many parents they have, the process of cell division, and how the organisms are able to evolve to the environment. The first aspect to conceive for the difference between the two types of reproduction is their parent. Asexual and sexual reproduction are alike because they both need at least one parent, however asexual reproduction needs only one parent, while sexual reproduction needs one or two parents. In addition, when asexual reproduction reproduces, it will make two genetically identical cells, two offspring. However, for sexual reproduction, there need be two sex cells that fuse because the offspring will be a combination of the male and female DNA in the nuclei of theses two cells. The offspring will form from one haploid cell (with 23 chromosomes/haploid, if human) from each parent to form a diploid (46 chromosomes, if human) cell of a new organism that is genetically unique from both parent cells. In addition, in mitosis, there are only four steps of cell division, which are prophase (chromatin condenses into chromosomes), metaphase (chromosomes align at the equatorial plate), anaphase (sister chromatids separate and centromere divide), and finally telophase, which is when chromatin expands and cytoplasm, divides (The 4 Stages of Mitosis). On the other hand, for meiosis cell division there are interphase (46 chromosomes), prophase (chromosomes double), prometaphase (nucleus dissolves), metaphase 1 (chromosomes align at middle of cell), anaphase 1 (separate chromosomes), telophase 1 (microtubules disappear and cell division begins), interphase 2 (two cells formed each with 46 chromosomes), metaphase 2 (microtubules attach to centromeres), anaphase 2 (chromosomes pulled apart to 23), telophase 2 (microtubules disappear and cell division beings), and lastly cytokinesis which is when 4 cells formed each with 23 chromosomes (Solomon). Therefore, sexual reproduction is more complex than asexual reproduction because it combines the DNA of a male and female sex cell to create a unique organism. An additional aspect to consider about the two types of reproduction is how they proceed the steps in the process. Even though both form, of reproduction go through the process of cell division, the asexual and sexual reproduction cell division process are different. There are two main types of asexual reproduction, which is binary fission and budding. Binary fission “occurs when one parents splits into two offspring” and this is how all bacteria and other low invertebrate simple organisms reproduce. In addition, budding “occurs when a new organism grows off a parent” (Pelletiera). On the other hand, sexual reproduction can...
