Answer: One of the ways that people of ancient times classified plants and animals is by use. Today, group the creatures, as they do the plants, on the premise of shared physical attributes. They put them in a progressive system of groupings, starting with the kingdom Animalia and continuing through phyla, classes, orders, families, genera and species.
Explanation:
We know that Hardy-Weinberg conditions include the following equations:
where 
And where p = dominant, and q = recessive; this means that 
is equal to the homozygous dominant, 
is the heterozygous, and 
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 
or 0.04. Let that equal our 
value.
So when we solve for q, we get:
Now that we have our q value, we can use the other equation to find p:
So then we can solve for our heterozygous population:
This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:
So now we know that there are 32 heterozygous cats in the population.
