explain why it is not possible to change hereditary conditions.

Brief Explanations:

Hereditary conditions are determined by genes. Genes are passed - down from parents and are part of an individual's genetic makeup. While some symptoms may be managed, the underlying genetic code that causes the hereditary condition cannot be easily altered as it is present in every cell with the same genetic information.

Answer:

Hereditary conditions are based on an individual's genetic code which is inherited from parents. The genetic material in cells is difficult to change comprehensively, so it's not possible to change hereditary conditions at their root, although symptoms can sometimes be treated.
