Explanation:
Detailed explanation-1: -A genetic mutation is a change to a gene’s DNA sequence to produce something different. It creates a permanent change to that gene’s DNA sequence. Genetic variations are important for humans to evolve, which is the process of change over generations. A sporadic genetic mutation occurs in one person.
Detailed explanation-2: -Mutations. A gene mutation is a permanent change in the DNA sequence of a gene. Mutations can occur in a single base pair or in a large segment of a chromosome and even span multiple genes. Mutations can result from endogenous (occurring during DNA replication) or exogenous (environmental) factors.
