</u>
<h2>

Explanation:
Myelin is a protective and insulating layer formed around the neurons of the central and peripheral neurons. The Schwann cells in the PNS and oligodendrocytes in the CNS form the myelin sheath around the neurons.
This myelin protects the axons of the neurons as well insulate the neurons which speed up the transmission of the electrical impulse generated in the neurons. If myelin is damaged, these impulses get slow or get damaged.
Thus, true is the correct answer.

Explanation:
Obligate carriers, or obligate heterozygotes, are those individuals that may be unaffected clinically, but must possess a copy of the mutant gene. For autosomal recessive conditions, obligate carriers can be the offspring of a parental mating of two carriers (50% of offspring will also be carriers). They can also be produced by a parental mating of a carrier by an affected individual (50% of offspring will be carriers).
