Migration refers to a movement of individuals from one population to the other. Migration has the ability to change allele frequencies (Jobling et. al., 2013). Migration also causes gene flow from one population to another. Migration can introduce new genes in a particular population. This might increase genetic diversity of that population. Migration can also result in similar genes in two or more distant populations thus reducing genetic diversity. Depending on its nature, migration can be a great source of genetic variation.
Sexual reproduction involves combination of gametes from two individuals to form a zygote. During sexual reproduction, there is an exchange of chromosomes between the two parents. The crossing over of chromosomes between the two parents leads to genetic variation among individuals who undergo sexual reproduction.
Population size will influence genetic diversity especially for finite population sizes. This is because finite population size will ensure changes in allele frequency due sampling error. The phenomenon by which random changes occur in allele frequency infinite population size results in genetic drift (Jobling et. al., 2013). This force has the ability to alter populations over time thus affecting genetic diversity. The influence of change in allele frequency over time relates inversely with population size. The larger the population size, the less the change occurs in allele frequency. It is, therefore, evident that larger populations will experience less genetic variation due to the minimal changes that occur in allele frequencies.
It is difficult to find a population that is in genetic equilibrium. In most cases, changes in allele frequencies are occurring over time ...Download file to see next pagesRead More

The repair pathway has been linked to colon cancer in humans via association between MI in colon tumours found in HNPCC families. MIs are short and repetitive sequences that are incorrectly copied by the DNA polymerase since the template and daughter strands found in the region are prone to misalignment.

Ethical Issues of Assisted Reproduction
Among the ethical issues of surrogacy is the exploitation of the poor who donate sperms and eggs for surrogate parents who have the wherewithal to have test tube babies and to determine the genetic make-up of these babies. The issue of premature babies has also been dodged by ethical questions on the need to save a life that would be marred suffering, illnesses, and handicaps.

Human Genetic Diversity
The nucleus of the cell divides in four nuclei. This process of producing reproductive cell is called Meiosis.Meiosis, being sexual type of reproduction, results in genetic diversities among offspring. Reasons for this are Independent assortment of chromosomes, crossing over and random fertilization.

Discuss about the movie Super Size me, and how its related to Pop CultureMcdonaldization
It is evident from the very beginning of 'Super Size Me' that film director Morgan Spurlock attempts to capture a pop culture phenomenon on film, and although his condemnation of McDonald's is evident, well-argued, and wittily conveyed, the underlying argument is far more inducing; far from blaming McDonald's and the McDonaldization of America as the utter cause of American obesity, at the end of the day we as individuals are the most important and powerful guardians of our health.
