Axons of the spinal nerve that innervate the ventrolateral body surface, structures of the body wall, and limbs make up the Ventral ramus.
The anterior portion of a spinal nerve is known as the ventral ramus. Shortly after a spinal nerve exits the intervertebral foramen, it branches into the dorsal ramus, the ventral ramus, and the ramus communicans. These contain information that is both sensory and motor.
The sensory and motor fibres that innervate the muscles, joints, and skin of the lateral and ventral body walls as well as the extremities are carried by the spinal nerves' ventral ramus. They continue to be separate from one another throughout the thoracic region and each innervates a small section of muscle and skin along the sides, chest, ribs, and abdominal wall.

The answer is Fist hope I helped
The Hardy-Weinberg equation is as follows:


Where:
(convert all % to decimals)
p= homozygous dominant
q= homozygous recessive
pq= heterozygous
While you did not specify whether the 0.2 frequency was for dominant or recessive, we can still figure out the answer.
Using the 1st equation, we can solve for the other dominant/recessive frequency:
1-0.2=0.8
Meaning that:
p= 0.8 & q=0.2
If the heterozygouz frequency is 2pq, then it becomes a simple "plug & chug" sort of approach.
2(0.8)(0.2)= 2(0.16)= 0.32
So, the heterozygous frequency would be:
0.32
Hope this helps!
