Question

explain how hereditary diseases are passed from one generation to another.

Explanation:

Hereditary diseases are passed via genes. Genes are segments of DNA. During reproduction, parents pass on their genes to offspring. Mutated or abnormal genes can carry disease - causing information. These genes can be dominant or recessive. Dominant genes cause disease when only one copy is present, while recessive genes require two copies (one from each parent) to cause disease.

Answer:

Hereditary diseases are passed from one generation to another through genes. Genes, which are segments of DNA, are transmitted from parents to offspring during reproduction. Mutated or abnormal genes can carry disease - causing information. Depending on whether the gene is dominant or recessive, the disease may be expressed with one or two copies of the mutated gene respectively.
