Genetic diversity

An insight into the methods of Conservation Genetics Understanding the need to use genetic methods in conservation biology will greatly aid in the process of bringing back any species that play an important role in their native habitat. Implementing genetic tools and methods in conservation programs helps to minimize the loss of genetic diversity, which allows populations to adapt to environmental changes and stressors. This helps to minimize the loss of the population numbers by reducing the…

which threats the global public health. Hence, the main purpose of the paper “Evolutionary Genetics of Human Enterovirus 71: Origin, Population Dynamics, Natural Selection, and Seasonal Periodicity of the VP1 Gene” was to discover the origin, genetic complexity, and…

Claim Scenario 1 demonstrates genetic drift. Evidence In scenario 1, 50 organisms were placed in a container to represent the parent generation. Twentyfive of the 50 organisms were marked, and 25 were unmarked (50% marked, 50% unmarked).The marks on the organisms represent a trait, the unmarked organisms don’t have that trait. After that, roughly half of the organisms in the previous container were put in container 2, these represented the organisms that survived, also known as generation 2. In…

Introduction It is estimated that there are one trillion species on earth despite all being originated from one common ancestor, LUCA. In this essay the importance and origin of diversity within species and between species is explored using Coleoptera as the taxonomic group. Coleoptera is the most dominant order of insects with 350,000-400,000 species, this is 40% of all insect species (Gillott, 1995) and the largest order in the animal kingdom. The degree of differences between individuals is…

and drawbacks in genetic engineering, designer children, and bionic athletes. The benefit is that improving technological advancement, we will be able to treat and prevent many diseases that are prevalent today. The downside is that exponential growth of technologies will allow us to manipulate our own nature, to enhance our cognitive abilities, physical strength, and choose genetic traits of our children to make ourselves “better than well” (Sandel, 2004). Sandel argues that Genetic engineering…

Genetic Modification: Scientists Against Ethics I. INTRODUCTION Imagine living in a world where some people were just born perfect. They consist of perfect looks, perfect personalities, perfect athleticism, perfect minds, and perfect everything. But you, on the other hand, just got the luck of the draw. From two parents, very average in terms of the word today, you were born, normal. Unfortunately, normal is not good enough. There are two types of people now: the normal ones and the flawed…

Genetic modification is the elimination of a certain gene containing undesirable trait and adding another gene containing the desired trait. The process includes getting the desirable material from a donor and not from the parents. Parents now can get all the characteristics they desire in their babies. They can also eliminate certain health problems the child might inherit from his/her parents. Genetic modification and manipulation has become a controversial topic since it has ethical and…

The random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) method was used to examine the genetic variability of Aiolopus thalassinus (Fabr.) populations at heavy metal polluted and unpolluted locations of different geographical distances. Four primers yielded a total of 69 scorable bands, which are all polymorphic. Cluster and Principal component analysis separated the inside and outside Cairo populations into two main branches that were further separated into smaller ones,…

modern genetics, then you should know that these nifty little segments of DNA, called genes, tell your body what to do and when to do it. For years scientist have been trying to figure out a way to manipulate these genes and modify them to achieve a desired effect in an organism, such as giving a mouse the ability to go longer periods without food, while eliminating the risk for undesirable mutations, like cancer. Genetically modified organisms such as mice have been altered at the genetic level…

that two coastal populations of pumas (Santa Ana Mountains and Santa Monica Mountains) had especially low genetic variation and gene flow (Ernest 2013). There are natural barriers to the puma’s movements such as the ocean, but the…
