Answer:
At a level in the spinal cord
Explanation:
The gate theory was elaborated in 1965 by P.D. Wall and r. Melzack, to explain the influence of tactile skin stimulation on pain relief. It essentially admits that there exists in the medullar posterior horns (located behind the central canal of the spinal cord) a gate-acting neural mechanism that can control the passage of nerve impulses transmitted from the peripheral fibers to the CNS through the medulla.
The gate regulates the influx of nociceptive impulses even before a perception of pain is created. The variation in the passage of action potentials (nociceptive) that the gate produces is determined by the activity of the thick (A-alpha and A-beta) and thin (A-delta and C) fibers, as well as cognitive influences.
The alleles of offspring vary, some are dominant and some are recessive, meaning that some traits get passed down and some don't, for example,: a dominant trait might be blue eyes, a parent would have blue eyes, and pass that dominant trait to their child so that the child would also have blue eyes, recessive traits are traits that skip a generation.
For example a grandparent might have black hair, but their child won't have black hair, however, their grandchild will have black hair, therefore the black hair trait is recessive and skipped a generation
