Transposable elements litter the genomes of primates, and a few of them are still capable of moving to new regions of the genome
If a transposable element jumped into an important gene in one of your cells when you were a baby and caused a disease, is it likely that your child would also have the disease? Explain.
It is not likely that your child would have the disease, because it is unlikely that the mutation is carried in the germ line. Probably the mutation occurred in a cell that gave rise to somatic cells and not germ cells. Only mutations in germ cells are passed on to progeny.

Endotoxins are heat-stable lipopolysaccharide (LPS) component of the outer membranes of Gram-negative bacteria. These endotoxins are highly antigenic and can be inactivated to form toxoids and used as vaccines.
