There are 100 cats in a population that follows hardy-weinberg conditions. 4 cats display a recessive white coat color. how many
mr Goodwill [35]

We know that Hardy-Weinberg conditions include the following equations:


p^{2}+2pq+ q^{2}=1


where p+q=1


And where p = dominant, and q = recessive; this means that p^{2} is equal to the homozygous dominant, 2pq is the heterozygous, and q^{2} is the homozygous recessive .


So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of \frac{4}{100} or 0.04. Let that equal our q^{2} value.


So when we solve for q, we get:


q^{2}=0.04

q=\sqrt{0.04} =0.2


Now that we have our q value, we can use the other equation to find p:


p+q=1


p+0.2=1


p=0.8


So then we can solve for our heterozygous population:


2pq=2(0.8)(0.2)=0.32


This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:


0.32*100=32cats


So now we know that there are 32 heterozygous cats in the population.
