Explain why it is not possible to change hereditary conditions.

Hereditary conditions are passed to us at birth through our genetic code called DNA.

Hereditary conditions include some of genetic diseases we receive either from our parents through chromosomes or those diseases are caused because of mutation of genes which is kind of problem in your genes. Because you cannot replace all this system, thus you cannot take out hereditary condition out of your body.

Hereditary conditions are passed to us at birth through DNA. Your DNA cannot change no mater what you do to your body. If your hair is naturally brown even though you dye it a different color your dna still when tested says you have brown hair. Same with skin color and other things.
