Answer:
True.
Explanation:
Polygeny occurs in organisms with complex genomes, when several pairs of genes interact to determine a trait, each with an additive effect on the other. Thanks to this type of interaction there is a very wide variety of phenotypes and genotypes for some characteristics. The interaction of these phenotypes with the environment further increases this variation, such as skin color and height, etc. In other words, polygeny is the state of a particular trait determined by the relationship or action of various genes.

C) heliocentric theory is what I think is the correct answer
The myelin sheath that covers many cns axons is formed by oligodendrocytes.
Oligodendrocytes are type of neuroglia (non-neural cells found in central nervous system) with protective, trophic and supportive role. Their function is to insulate axons (with myelin sheath), in the central nervous system (CNS) which is, equivalent to the function performed by Schwann cells in the peripheral nervous system (PNS).
