Question

explain why it is not possible to change hereditary conditions.

Explanation:

Hereditary conditions are determined by an individual's genetic makeup, which is inherited from their parents. Genes are segments of DNA that carry the instructions for various traits and characteristics. Since the genetic code is fixed at conception (barring rare genetic mutations), we cannot alter the underlying genetic factors that cause hereditary conditions. External factors or lifestyle changes can sometimes manage symptoms but do not change the inherited genetic blueprint.

Answer:

Hereditary conditions are caused by inherited genes (DNA - based genetic code fixed at conception). As the genetic blueprint can't be changed (except rare mutations), hereditary conditions can't be altered at their genetic root (though symptoms may be managed).
