DNA replicates itself, so no, unlike what it may seem, parent organisms do not loose their DNA. Before the fecundation process, a cool process similar to miosis happens, it is called meiosis. During meiosis the parent chromosome will duplicate it self and break down each of its 46 chromosomes into 4 different new formed cells, which will become the sperm and egg cells. Each of these egg or sperm cells will be different from eachother, which is how you get siblings that don't look alike, however they will contain a copy of the parent's genetic information.
In conclusion;
In the creation of offspring, the copy of the parent's DNA breaks apart into 4 different pieces which will form sperm or egg cells.

The myelin sheath is an extended and modified plasma membrane that is spirally wrapped around the axon of the neuron. The primary purpose of the myelin sheath is to a. insulate the neuron so it can transmit information more efficiently and quickly. A myelinated neuron can transmit the electrical impulses at the speed of 400 Km/h whereas the speed is just 4 Km/h in a non-myelinated or a damaged neuron.
