Genetics and Reproduction Asexual and Sexual Reproductions - 275 Words

Genetics and Reproduction: Asexual and Sexual Reproductions (Essay Sample) Content: Genetics and ReproductionNameInstitutional AffiliationGenetics and ReproductionIn my opinion, sexual reproduction is the better than asexual reproduction. This is because sexual reproduction provides genetic diversity since sperms and eggs produced contain different combinations of genes compared to the parent organism. In the case of femaleÂcopperheadÂsnakesÂthatÂhave the abilityÂto reproduce asexually, thereÂis limitedÂgenetic diversity because creation of an offspringÂis achievedÂfrom one parent. It is important to note that asexual reproduction results in a clone parent or an offspring withÂidenticalÂDNA as the parent. The value of genetic diversity isÂimpairedÂthrough asexual reproduction and the results are no variation from generation to generation in a species population (Hartfield, Wright, Agrawal, 2016). The process of acquiring genetic diversity, thereÂmust bedifferent genetic combination from both sp ecies. For instance, the femaleÂcopperheadÂsnakesÂwill lack genetic diversity because of similar phenotypes and genetic composition forming the offspring.Gregor Mendel's law of Âsegregation Âin genetics, for any particular trait, the pair ofÂalleles Âof genes from each parent should separate with one alleles passing from each parent on to an offspring. This is not the case when we look into the asexual reproduction in femaleÂcopperheadÂsnakes. The principle of segregation explains meiosis and sexual cell formation that occurs in sexual reproduction (Hartfield, Wright, Agrawal, 2016). Moreover, the onlyÂsourceÂof variation in asexual organisms is mutation and stands anÂultimateÂsource of variation in sexual organisms. It is important to note that duringÂthe formation ofÂgametes two alleles from each parent are responsible for a trait separate from each other. Therefore, the offspring will have diversity since the genetic fo rmation entails genetic traits from both parents.FemaleÂcopperheadÂsnakes have been biologically confirmed to reproduce asexually. However, the Gregor Mendel's principle of segregation depicts that it is possible for a parent to have two different alleles for a certain gene with each one being a copy of a given chromosome (Hartfield, Wright, Agrawal, 2016). Therefore, these two allelesÂwill be separatedÂby the process of meiosis where the two copies of each chromosomeÂare locatedÂon the chromosomes. ThisÂis followed by theÂprocess ofÂself-segregationÂby the alleles.ÂDuring the cross over period of meosis, Gregor Mendel denote...
