In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.2. The frequency of individuals that are heterozygous for this allele is 0.32.
<h3>Hardy Weinberg Equilibrium Principle </h3>
- A stable, idealized population's constant frequency of alleles and genotypes is described by the Hardy-Weinberg equilibrium principle.
- In a sizable population, random mating, or spontaneous mutations are necessary for Hardy-Weinberg equilibrium.
The Hardy-Weinberg equation dictates that the sum of the allele frequencies for each allele at the locus must equal 1, therefore p + q = 1. The Hardy-Weinberg equation is also written as p2 + 2pq + q2 = 1, where p is the population's frequency of the "A" allele and q is that of the "a" allele.
The homozygous genotype AA frequency is represented by p2, the homozygous genotype aa frequency by q2, and the heterozygous genotype aa frequency by 2pq in the equation.
Here, q = 0.2. Because of this, p = '1- q = 1 - 0.2 = 0.8.
The population of individuals who are heterozygous will now be 2pq, or 2 * 0.8 * 0.2 = 0.32.
Hence, This indicates that the population is heterozygous with a frequency of 0.32.

The warning sign which is represented by a patient appearing flushed and is perspiring in the case of a medical emergency is dehydration.
<h3>What is Dehydration?</h3>
This is a condition which involves the body losing more fluids than it can and is usually very dangerous due to it causing a a rapid heart rate and a decrease in her blood pressure.
This therefore prevent blood from reaching vital organs and cells in the body which may lead to death. It is therefore advisable to give the affected individual more water or other liquids.
The liquid or fluid helps to restore the balance in the body system in other to prevent the various complications which comes as a result of this condition.
This is therefore the reason why dehydration was chosen as the most appropriate choice.

Answer: Cross pollination. The bee is taking from a new plant and giving it to the old plant so the old plant can be good as new. Good enough for ya mods?
If a population experiences a form of genetic drift, then their genome/genetic code would change. This then can cause the frequency to follow as well. Best example I can think of right now is moths in the Industrial Revolution: all of the soot released into the air caused the moths to be easily seen by birds that ate them (they were all white). This then caused those that were darker, like dark brown to match its new surroundings, weren't eaten by the birds because they could blend in. This caused the phenotype frequency (and therefore genotype) to change to having dark moths being more common than light. And we still see that today! Most moths are still dark brown.
