Can you help me to understand Hardy-Weinberg equilibrium?
My goal is to be able to solve the following kind of problem Here is a tutorial to perfectly understand Hardy-Weinberg Rule!

Visit Stack Exchange I really fail to understand Hardy-Weinberg equilibrium and can't find an easy enough source of information.
To estimate the frequency of alleles in a population, we can use the Hardy-Weinberg equation.

According to this equation: p = the frequency of the dominant allele (represented here by A)q = the frequency of the recessive allele (represented here by a) For a population in genetic equilibrium:p q = 1.0 (The sum of the frequencies of both alleles is 100%.) (p q) = frequency of aa (homozygous recessive) This page contains all the information you need to calculate allelic frequencies when there are two different alleles.Calculate allelic and genotypic frequencies for this population. Unfortunately, you all crash land (safely) on a deserted island.No one finds you and you start a new population totally isolated from the rest of the world. are heterozygous for) the recessive cystic fibrosis allele (c).Assuming that the frequency of this allele does not change as the population grows, what will be the incidence of cystic fibrosis on your island?You sample 1,000 individuals from a large population for the MN blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes).Although malaria cannot grow in these red blood cells, individuals often die because of the genetic defect.However, individuals with the heterozygous condition (Ss) have some sickling of red blood cells, but generally not enough to cause mortality.A very large population of randomly-mating laboratory mice contains 35% white mice. Now that we know the frequency of each allele, we can calculate the frequency of the remaining genotypes in the population (AA and Aa individuals).White coloring is caused by the double recessive genotype, "aa". AA = p After graduation, you and 19 of your closest friends (lets say 10 males and 10 females) charter a plane to go on a round-the-world tour.In addition, malaria cannot survive well within these "partially defective" red blood cells. First, what is the percentage of butterflies in the population that are heterozygous?Thus, heterozygotes tend to survive better than either of the homozygous conditions. Well, that would be 2pq so the answer is 2 (0.37) (0.63) = 0.47.
