When it comes to population evolution and genetics, we cannot fail to cite the Hardy-Weinberg principle which emphasizes that if evolutionary factors such as natural selection, mutation, migration and genetic oscillation do not act on a particular population, the frequencies genotypic proportions will remain constant.
The five requirements for a population to be in Hardy-Weinberg equilibrium are:
- Large-scale breeding population: For a population to be in Hardy-Weinberg equilibrium, it is important that this population is large, as small populations favor genetic drift (unanticipated fluctuations in allele frequencies from one generation to another).
- Random mating: In order for the Hardy-Weinberg equilibrium to occur, it is necessary that the mating occur at random, with no preference for certain groups within the population. In this case, we say that the population is in panmixia, that is, they all mate at random.
- No mutations: Mutations alter the total alleles present in a population (gene pool). Therefore, in a Hardy-Weinberg equilibrium population, no mutations should occur.
- No gene flow: When there is gene flow due to migration or immigration of individuals, some genes may be included or excluded from the population. Thus, in an equilibrium situation, no gene flow occurs.
- Lack of natural selection: For a population to be in Hardy-Weinberg equilibrium, natural selection must not be acting on it. If natural selection acts, some genotypes will be selected, modifying the allelic frequencies of the population.
<span>The most serious complication that can appear in a client experiencing kidney failure is fluid retention. This could lead to swelling in your arms and legs or fluid in your lungs wich can cause a pulmonary edema so a client can happen a sudden death if not treated accordingly.</span>
Insertion mutation takes the T out and replaces it with an A.
The answer is : Light waves would be more likely to be refracted or diffracted, thus failing to reach plants and phytoplankton
Sunlight is needed by the producer(plants, phytoplankton) in the ocean to do photosynthesis. When an are is attacked by severe storm, the area will be covered by cloud of the storm which impede the light, cause it to be refracted or diffracted. This will cause less light comes to the producer of the plants and phytoplankton.
Artificial active immunity. I'm a bio major, hope I helped :)
