If a trait is determined by two alleles, the sum of p and q is 1. Why is this true?

The value of q is

q = 0.10

Explanation:

The sum of the frequency is equal to 1.

Therefore, we have the following equation:

p + q = 1

Substituting values we have:

0.90 + q = 1

Clearing the value of q we have:

q = 1 - 0.90

q = 0.10

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
