In humans, Rh-positive individuals have the Rh antigen on their red blood cells, while Rh-negative individuals do not. If the Rh
-positive phenotype is produced by a dominant gene (A), and the Rh-negative phenotype is due to its recessive allele (a), what is the frequency of the Rh-positive allele if 84% of a population is Rh-positive?A. 0.04.B. 0.16.C. 0.48.D. 0.60.E. 0.84.
"They are <span>multicellular" is not a characteristic of bacteria. Although it should be noted that the smallest life forms don't necessarily have to be bacterial. </span>
Evolution is the process through which the different organisms advances from having less developed form or the position into a less-perfect form. As, different species go through different pathways in which they attain a new and complex form of mechanism to survive inside a region or given parameters.
While, the process of evolution takes place in a three main different forms or ways, or briefly in three different pathways:
<u>The natural selection:</u> Species goes through different process in which they deal with the number of obstacles, like the limitation of food resources, having the competition for the shelter and resources etc. During, such a process the species either goes into extinction or they survive for a much longer time then expected.
<u>The Genetic flow:</u> The species have a given set of genes or more over genome which they posses for having a specific identity among the diverse form of organisms.The different species may go through the mutations or even may go through the different form of gene losses. As, due to the changes inside the overall environment or the system of the organisms the difference or diversity inside the genome of the organisms may occur.
<u>The Genetic drift:</u> The genetic drift is the displacement which causes the changes inside the different species over all existence. For example, lets genetic drift may be termed as the process which is brought by a set of species which are detached from its over all population and it brings change along with variety by introduction of that small population inside the given region.
