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.

Since the male and the female have recessive alleles of this gene, all of their offspring will be like that too.
rr x rr cross will result in 100% of the offspring with the genotype: rr
R- dominant (but none of the parents has this allele)
r- recessive
The overall charge of an atom is neutral because it has the same amount of protons and neutrons. They are positive and negative so they cancel each other out.
Answer:
Behavioral scientists that investigate and explain how factors such as genetics, neurobiology, and hormonal responses can influence psychopathology are using a <u>biological</u> perspective.
Explanation:
The biological perspective focuses on the effects of the body on behavior, feelings and thoughts. The study of the biological bases of behavior is a link between two disciplines: psychology and biology. In this sense, the biological perspective implies the study of the behavior and mental processes of the individuals attending to their biological components. The biological perspective, also called neurophysiological, assumes that the mental disorder is a disease, just like any other physical illness and that psychopathological alterations are caused by biological abnormalities, such alterations can be the result of genetic factors, metabolic or hormonal disorders, physical trauma among others. The alteration of the brain is the primary cause of the abnormal behavior.
