genetic diversity
Before discussing the topic of genetic diversity, it is imperative that you, the reader, can get an understanding of what all topics and points of focus that is taken into consideration when discussing genetic diversity. This includes a brief history as to how this came about, and what components allow this process to occur. Genetic diversity can be a complicated, yet interesting topic to cover.
From the name of the process of genetic diversity, it can be inferred that this deals with genes and genetics. The first thing to address would be the field of study that this involves. This would be the field of genetics. Genetics is the study of biologically inherited traits called genes, including traits that are partially influenced by the environment.
The existence of genes first became a hypothetical theory in 1866. It was introduced by Gregor Mendel. His studies was not taken serious until 1902 when researchers found some of Mendel’s old work. Within the next twenty years, many methods for gene mapping and for experimentally induced mutations were developed. Starting in 1940, researchers in this field started using microbes in their experiments. This microbes includes fungi, bacteria, and bacterial viruses. In the next few years, a merging of the study of genetics and biochemistry led to a division of genetics called molecular genetics. In 1953, experimentation of deoxyribonucleic acid, DNA, led to advancement in molecular studies. During the 1970s, gene cloning and DNA sequencing methods were developed. The next big step in science happened in the 1980s when methods for DNA marker analysis, DNA fingerprinting and polymerase chain reaction, PCR, were all developed. During the 1990s, whole genome sequencing methods were developed. This new method led to the make of the study of all the genes in a genome. This field of study is called genomics. The accessibility of whole genome sequences also led to the make of the study of all proteins coded by a single

    6. Briefly describe the two meiotic events that contribute to genetic diversity in a population. Each gamete (sex cell) is unique due to a process during meiosis called cross-over which (simplified) swaps around some genes to create unique chromosome combinations. meiosis helps to create a population that is not only physically and genetically different but also one, which is perfectly fit to survive.…

    Genetic diversity provides a species with its form and function. A species genotype refers to their genetic code; what their cells are going to be used for – hair cell, eye cell, muscle cell, etc. A species phonotype refers to the way in which that species gene will be expressed – blonde hair, blue eyes, large muscle tone; which significantly impacts the success of that individuals genes. Without genetic diversity among populations the gene pools would be very limited, which gives way to a rise in mutations and inevitably the end of a species. “Genes regulate body size, shape, physiological processes, behavioral traits, reproductive characteristics, tolerance of environmental extremes, dispersal and colonizing ability, the timing of seasonal and annual cycles (phenology), disease resistance, and many other traits…to ignore genetic variation is to ignore one of the fundamental forces that shape the biology of living organisms” (Falk, D., Knapp, E., & Guerrant, E., 2001). Genetic diversity also affords different organisms to change with the ever-changing environment around them. Environmental variation, over time, is known as natural or historic range variation. This can include: variation in population sizes of species due to natural predators and disease, changes in weather, changes in the availability of resources etc. Since the environment is always changing is allows populations to be genetically diverse. If species X were to live in a ‘perfect’ environment, there would be very little genetic diversity and biotic integrity – everything would remain status quo. We would not see species evolving or changing for any reason as there would be no need. Species all over the world are adaptable and change with their habitat – evolving tolerances to changes in the soil and weather and changing to continually be…

    The diversity in the world today helps us all to grow as individuals and open our minds to the different ways of life. When a person becomes exposed to the different cultures and ways of life and how others live their life’s we see that all people do live differently in some way or another, then our minds are not closed anymore, yet they are opened to the differences of the world and we can see that each culture has a difference and that difference has a meaning in their lives. Diversity also promotes tolerance in the world. It allows us to accept other cultures and sometimes even adapt to the ways of those cultures and utilize those differences in our own cultures and lives. Although we are all different in some way or another, we all have differences that can strengthen society. Diversity allows us to learn, grow and understand new ways of living. It also allows us the opportunity to experience life to the fullest. If we had no diversity, we would all be in our own little worlds. With diversity we are able to expand our knowledge and learn more and become less ignorant to the different ways of the different cultures in the world.…

    The main source of genetic variation is meiosis. Within meiosis, fertilization occurs and creates variation. Within meiosis, although it is rare, mutations happen which can be also a source of variation. Gene flow, the movement of genes within multiple populations is another source of variation as well. Variation plays the role of making different traits in populations to lead to favorable and non-favorable traits to the environment which natural selection and selective pressure acts upon in the process of evolution. Variation is important…
