During a microscopic comparison of two hairs, a trace analyst compares the medullae of the hairs to determine species of origin

What is the difference between the medullae of human and animal hairs? Name one exception to this among humans that may help in these determinations.
What will be an ideal response?


Answer should include points such as the following:
Most animals have medullae that are either continuous or interrupted. Human head hairs generally exhibit no medullae or have fragmented ones; they rarely show continuous medullation.
One exception is in the Mongoloid race, whose members usually have head hairs with continuous medullae.
