What is the final result of genetic drift in populations of

Biology
2 answers:
Inessa [10]3 years ago
6 0

Answer: Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100% frequency, of other alleles.Once it begins, genetic drift will continue until the involved allele is either lost by a population or is the only allele present at a particular gene locus within a population. ... Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool.

Answer:

decrease the genetic diversity of a population.

Explanation:

Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time.

Genetic drift can cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.

How are humans immune to infectious diseases after they have already contracted the disease previously? and How do vaccinations
Varvara68 [4.7K]

Answer:

Explanation:

Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system. Antibodies are proteins produced by the body to neutralize or destroy toxins or disease-carrying organisms. Antibodies are disease-specific. Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system's antibodies and other cells to target the invader. A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.

It tells the audience if the results support or contradict the hypothesis

Explanation:

When a scientist describes the materials that she used and how she performed her experiments, it tells the audience if the results supports or contradicts the hypothesis.

  • A hypothesis formulation helps to test a scientific claims.
  • Experiments are usually hinged on well designed hypothesis.
  • From the hypothesis, one can be sure the experiment is tuned and designed within the scope of the observation desired to be tested.
  • This is why the materials used and procedures followed in an experiment can tell if the results supports or contradicts the hypothesis.
