Discuss the issues related to genetic diversity: mutations, sexual reproduction, migration, and population size

Genetic diversity:
Genetic diversity ids defined as the diversity or genetic variability within species. Every species possesses genes which are the source of its own unique features. In human beings, for example, each person's genetic individuality is reflected by the huge variety of people's faces. The term genetic diversity also involves distinct populations of a single species, for example the thousands of breeds of different cats or dogs or the numerous variety of mangoes. The significance of Genetic Diversity is important as it helps in maintaining the gene pool. An individual or a whole population's ability to tolerate

Gametes are produced by a process called meiosis which starts by the duplication of the chromosomes, followed by two cycles of cell divisions and halving of the chromosome number. Gametes have half the number of chromosome of other adult cells of an organism. Meiosis consists of a reduction division and an equational division. Gametes are produced by two divisions, meiosis I and meiosis II. Meiosis I is a cell division that occurs only in germ cells and meiosis II is similar to a mitotic cell division. Before germ cells enter meiosis, they are generally diploid, which means that they have two homologous copies of each chromosome. A germ cell duplicates its DNA just before it enters meiosis, so that the cell contains four DNA copies distributed between two pairs of homologous chromosomes. It can be argued that Prophase I is the longest and most important segment of meiosis because during this interval recombination occurs. Prophase I begins with the alignment of homologous chromosome pairs. This is a source of genetic diversity

Genetic Diversity, Migration and Population:
Genetic diversity is defined as naturally occurring genetic differences among individuals of the same species. This variation permits adaptability and survival of a population during the changing of environmental circumstances. A nonrandom mating can sometimes happens when a
