Answer:
one motor neuron
Explanation:
Although a single motor neuron can innervate several muscle fibers, each muscle fiber is innervated by only one motor neuron
Based on these facts, we can state that the genes of the two organisms had a eukaryotic origin.
We can arrive at this answer because:
- Despite having exons, prokaryotes do not have introns in their genomes.
- This means that if two organisms have the same sequence of introns and exons, they have a common ancestor, in addition to having their genes originated in a eukaryotic organism, which explains the sequence of introns.
This means that the genetic expression of these two organisms has similarities, even if they are organisms with different biological processes.
