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.
