Answer:
The size of the ventral horns reflects the amount of skeletal musculature innervated at each level.
Explanation:
The central nervous system consists of the brain and the spinal cord.
Both the brain and the spinal cord have white and gray matter present in them.
In the spinal cord, the arrangement is such that the gray matter is arranged on the outside whereas the white matter is arranged on the inside of the spinal cord.
The grey matter is itself arranged in sections which are known as horns and thus there are dorsal horns as well as ventral horns.
Amongst the ventral and dorsal horns the size of the ventral horns varies because of the variation in the amount of skeletal muscle that innervates at each level.
Answer:
Codominance
Explanation:
This case happens when both alleles are dominant then they will be equally expressed in phenotype
I can give you an example to understand this topic such as blood type: in the type AB both A and B are codominant = 2 dominant alleles are expressed together
