A dominant position) in a population of fantastic animals, brown fur (B on white skin (b) The total population is 514 people, 214 of them are white.
A. What is the frequency of white skin phenotype? What is the genotype? How often is genotype?
B. What is the frequency of alleles of the b? B?
C. What is the frequency of brown skin phenotype? What is the frequency of the genotype of individuals homozygous dominant? What is the frequency of heterozygous genotype?

Hardy Weinberg Problems 10 Points For Question Can Anyone Help Me With Hardy-Weinberg Problems?

Talks Hardy-Weinberg mediation of the two alleles in a population. The dominant allele = p. Allele = q.
So, if p = q = B and B
To use hardware, there are certain criteria that must be met: the general population undirected, no natural selection, no mutation, no migration.
Anyway, here's a little more information:
p + q = 1 = 100%. This means that only in their alleles of particular gene locus P and Q.
Since this is an equation that can do the same calculation for both sides and balance. So let's square both sides:
p ^ 2 + pq + q ^ 2 = 1 = 100%
If the equation is in this way we can (subject to the frequency of alleles phenotypes p and q).
pp = p ^ 2 = homozygous dominant
PQ = heterozygous
qq = q 2 = homozygous recessive
So now our equation tells us that the sum of all phenotypes = 100%.
Use this information to your question.
B is dominant, so that the animals can be heterozygous or homozygous dominant brown. They are BB or B =PP or PQ.
White then animals are homozygous recessive = BB = qq.
Now you can begin to enter their data in the above equations in touch.
A. =% phenotype frequency of the phenotypes of a species from a total of phenotypes. In this case, white = 214/514. You can write as often as a percentage or a decimal number.
The genotype frequency of recessive phenotypes is the same as the phenotype ratio.
B. It is more difficult. You must use the equation in the square. They know that AD = QQ = (214/514). How to find the frequency of allele B, only the square root of the previous section.
Q If you know you can p:
p + q = 1, p = 1 - q
C. You know enough to solve this game!
Enter Sci Fi 10-point .... good answer .... so great that you give any specific information, but it showed how the calculations.
