Topic: Asexual reproduction stifles potential change
Reproduction is “the act or process of reproducing; specifically: the process by which plants and animals give rise to offspring and which fundamentally consists of the segregation of a portion of the parental body by a sexual or asexual process and its subsequent growth and differentiation into a new individual”, as stated by the Merriam- Webster English Dictionary. Sexual reproduction is a process whereby the female gamete fuses with the male gamete to form a zygote, which potentially develops into genetically different offspring. Essentially this means, we combine the genetic information from two individuals of different types or sexes in order to produce a new individual. Asexual reproduction, or agamogenesis, on the other hand is, as stated by Wikipedia, “a mode of reproduction by which offspring arise from a single parent and inherit the genes of that parent only”. Basically, it is reproduction without the fusion of gametes and the offspring produced will be genetic copies of the parent. Asexual reproduction can be advantageous in many ways, for example, due to the fact that the formation of gametes is not necessary, the process of bringing them together is not required, and the involvement of another organism is non-essential, it occurs much faster than sexual reproduction. Asexual lineages can increase their numbers rapidly because all their members can produce viable offspring. Comparatively, in populations which reproduce sexually, some of the individuals are male, and therefore cannot produce offspring themselves; therefore in an idealistic situation with a sexual population half composed of males, an asexual lineage would have roughly double the rate of population growth. Additionally, asexual reproduction may be advantageous, for example, in cases of low population density, where organisms are able to reproduce without a partner- there does not need to be energy expended...
