Genetics and Society - Essay Example Diploid cells which are destined to produce the male and female reproductive cells undergo a type of cell division referred to as meiosis by which the chromosomes present in the parent cell is reduced to half to form four reproductive haploid cells called gametes. This process of separation and assortment of the homologous chromosomes occurs at random and the resulting haploid cells do not contain only paternal or maternal chromosomes but a mixture of genes from both parental chromosomes. This independent assortment of genes was first observed by Mendel when he was studying the genetics of pea plants and from his study he formulated the principle of independent assortment. The process of meiosis which is responsible for the production of gametes occurs via this principle of independent assortment. Meiosis begins with the replication of a pair of chromosomes in the diploid germ cells which are destined to become male or female gametes. The replicated chromosomal pairs are called siste r chromatids which are initially joined at the central point called the centromere. As the meiotic spindle forms at each pole of the cell with the help of microtubules, the two pairs of homologous chromosomes form tetrads within which any two chromosomes can overlap or recombine to form recombinant DNA which gives rise to new genetic combinations. This process is called crossing-over. Following this the pair of chromatids are pulled towards each pole of the cell and the chromosomal pair is enclosed within a nuclei. The cell then undergoes cytokinesis during which the cytoplasm divides into two giving rise to two daughter cells each containing a haploid chromosome. Thus meiosis is an important process during which pairs of homologous chromosomes are independently assorted to give rise to haploid gametes and also the chromosomes in the tetrad stage recombine to form new combination of genes which is

Giordanos Operation Strategy Essay Example | Topics and Well Written Essays - 750 words

Giordanos Operation Strategy - Essay Example This paper illustrates that it has been consistent in Giordano’s operation strategy and maintained its competitive pricing by having a centralized distribution center and uses outlets only for sale of garments. It extensively uses technology within its operations. Sales figures are used to forecast next day’s orders and fill the inventory at night. Keeping low inventory also helps it to react timely to changes in fashion and produce goods that meet the changing demands of the people. It, therefore, saves considerably through fast selling items and benefits are passed on to customers through quality garments that are low priced. Thus, its philosophy of ‘value for money’ has significantly contributed to its competitive success. Giordano has been quite successful with its market strategy which relies heavily on exemplary customer service and cost leadership. It has maintained its leadership position in low priced quality garments. The strategy has been very su ccessful during the financial crisis but it does not seem to be that effective when it increased its cost of garments that were trendier and catered to higher economic strata of society. Thus, in order to meet the demands of the segmented market, it introduced new label called Bluestar Exchange or BSE which were trendy and competitively priced. This has helped Giordano to be consistent with its market strategy of maintaining cost leadership. As Giordano expands its business interests into new market segment and territories, the biggest operation management challenges that it faces is that from other international brands like Zara, Gap, Espirit, Thames etc. which are already established brands in the mid and upper segment of the market. Apart from Bluestar Exchange that meets the demands of the low and mid-income group, it has introduced sister brands, Giordano Ladies and Giordano Junior that target higher end segment.
