Population Genetics Introduction
There are so many kinds of questions about which population genetics has to be answer. It explains the behavior of alleles in the populations by focusing on change produced by he forces that could cause allelic frequencies to change by time. “Allelic frequency change by time” is simply a term of the “evolution “Thus, population genetics is the branch of genetics that concerns with evolutionary processes of genetic drift, natural selection, mutation, …show more content…

Evolutionary forces change allele frequencies
Mutation… It is a randomly heritable change in the genetic makeup(DNA) which is an ultimate source of all new alleles combination .its effects on populations promote the differentiation but its effects are gradually in the absence of other evolutionary forces.
Migration…It is formation and introduction of new alleles into gene pool of population. Its effects on populations may result in gene flow hinders differentiation. It is cohesive type of force which bind populations together.
Random Genetic Drift… It is the random process where some alleles are not transferred to the next generation by chance itself. It’s major impact result in decrease in genetic diversity, decreased in heterozygosity, Increasing genetic differentiation among populations.
Natural selection…It is the differential, non-random reproductive success of individuals where differ in genetic hereditary characters .it promotes differentiation between populations that inhabit unlikely environments and hinders differentiation between populations that inhabit same

  • Difference Between Directional Selection And Disruptive Selection

    243 Words  | 1 Pages

    Directional selection and disruptive selection are two of the three types of natural selection. Although both of them result in a population adapting to biotic and abiotic environments, they differ in many ways. Directional selection occurs when one extreme phenotype is favored over the other phenotypes, whereas disruptive selection occurs when two or more phenotypes are favored over the others. Another difference is that disruptive selection favors polymorphism and directional selection causes species to evolve over time and leads to the extinction of those lacking the phenotypes causing the distribution curve to shift.

  • How Does Epigenetic Affect The Future

    893 Words  | 4 Pages

    Tuan Nguyen Epigenetic Epigenetic has been something that been receiving a lot of attention and for good reason as it challenge the way people think about the past, themselves, and the future. This paper will explore topics including what is epigenetic, how it relate to evolution, and what impact will epigenetic have in the future. To explore more about epigenetic one has to know what it is. Basically epigenetic is your gene turning on and off without changing the gene sequence itself.

    Population Trend (Demographic Transition Model) - There are 5 stages in population trend - Stage 1: High fluctuating – easy to get infected by the diseases, huger and natural hazards. (Ex. Tribes in Amazon) - Stage 2: Early expanding – having a more stabilized life, which having access to the basic supplies. (Ex. Very impoverished country) - Stage 3: Late expanding – most low-income countries. - Stage 4: Low fluctuating – most middle and high-income countries.

  • Birth Rates In Canada Case Study

    284 Words  | 2 Pages

    In Canada we need immigration to replace the retiring workforce, keep our economy strong, keep our population at an acceptable level and to increase birth rates. In Canada we are facing an increase in retirement rates because the baby boomers are starting to retire. Since they are starting to retire we will have to find a way to fill the job demands because the retirees jobs are becoming available. In Canada are birth rates are also declining which will cause us problems in the future to help increase these rates we need immigrants. In the future if our birth rates are low and the workforce is retiring we will have problems keeping up with the job demands so we need to bring skilled workers to Canada from other countries to fill these job

    Critical thinking questions: physical anthropology textbook 1. Given that you’ve only just been introduced to the field of physical anthropology, why do you think subjects such as skeletal anatomy, genetics, nonhuman primate behavior, and human evolution are integrated into a discussion of what it means to be human? The study of physical anthropology integrates the subjects of skeletal anatomy, genetics, nonhuman primate behavior, and human evolution because anthropologists look to the fossilized remains of hominins to see what their environments were like and what they ate. In addition to these sub fields, anthropologists look to skeletal anatomy to see any evolutionary change or if the hominin had died from any diseases and how old and tall

  • Adoption Studies: Genetic Differences

    an adoption study, the similarities between adopted children and their biological and adoptive offspring are compared. Adoption Studies are useful because they share their genetic information with their parents, even though the environment is different. This is the best way of separating genes from environment so the two can be tested However, Children requiring adoption are often placed with families similar to their own, so the differences may still be minimal Where the similarity is greatest with the adoptive parents an environmental influence can be assumed on the characteristic in question.

  • Bottleneck And Founder Effects Of Genetic Drift

    260 Words  | 2 Pages

    Genetic drift has two types the bottleneck and founder effects. With the bottleneck effect the one generation of a species is reduced so that genetic variations can take effect more quickly. One example of bottleneck is the Northern elephant seal that was hunted by humans in the late 1800’s. They were almost extinct but have made a small comeback. They still have marks of the bottleneck; however the southern elephant seal has much less genetic variation because they were not hunted as much.

    So, the genetic diversity or the variety of different genotypes will be severely reduced in modified communities. Also, the ability to survive directly depends on genetic diversity because populations without it will not be able to meet the demands of the environment (Wolfe, Christian). A disease that could be survived by a population with the normal human genetic diversity, would wipe out the modified community without the genetic diversity. Changing the genotype of just one can affect the whole diversity of humans and with the many processes, including sterilization and genetic screening, changing the genotype of one comes with ease. The ease of changing one leaves humans at a point where the achieved diversity can be easily destroyed, further placing them at risk through the threat of disease (Wolfe, Christian).

    Introduction This paper will explore the notion of genetic discrimination and its effects on the population currently then the future. This topic is quite controversial because of the flexible laws that are put in place. It is also a controversial topic because of its age. The length that genetic discrimination has been a problem is significantly shorter than many issues that are discussed in this manner.
