Final answer:

Gene mutations, their types, and effects on traits and health.


Explanation:

A single gene mutation is a permanent alteration in the DNA sequence of a gene, resulting in changes in traits. This is typically caused by a change in a base sequence in DNA, such as a single base-pair substitution in the gene for Hemoglobin leading to Sickle Cell Anemia.

Types of mutations include Missense mutation and Nonsense mutation, affecting protein function. Mutations play a crucial role in genetic diseases and evolution as a source of genetic variation.

Genetic diseases like Neurofibromatosis Type 1 result from mutations in critical genes, emphasizing the significance of understanding the impact of genetic changes on health and traits.
