The medulla has the ascending and the descending tract which function to link the brain with the spinal cord.
<h3>What is the role of medulla?</h3>
- Medulla oblongata is the lowermost part of the brain.
- It is located at the place where the brain and the spinal cord connect thus it carries nerve signals between the brain to spinal cord thus help the entire body to communicate.
- It controls biological processes like blood pressure, breathing and heartbeat.
- Ascending tract functions to carry sensory information from the body (e.g.: pain) from the spinal cord to the brain (upwards). 
- Descending tract carry motor information (e.g.: instructions to move the arm) from the brain down the spinal cord to the body (downward).
- Damage to medulla can lead to respiratory failure, paralysis, or loss of sensation.

Answer:
Hardy-Weinberg equilibrium AND IF you assume that red hair is a simple recessive trait, then
q^2 = 0.12
q = 0.35 and p = 0.65
p^2 would equal proportion of population that is homozygous = 0.42, so 42% of the population is homozygous for non-red hair.
