Detailed explanation-1: -A gene variant is a permanent change in the DNA sequence that makes up a gene. This type of genetic change used to be known as a gene mutation, but because changes in DNA do not always cause disease, it is thought that gene variant is a more accurate term.
Detailed explanation-2: -Changes to an organism that are a result of or result in genetic mutation alter the genetic makeup of an organism and can be passed on to the next generation. Mutations are changes in an organism’s genetic information that potentially affect the current functioning of that genetic information.
Detailed explanation-3: -Mutations are changes in the genetic sequence, and they are a main cause of diversity among organisms.
Detailed explanation-4: -The correct answer is mutation. Mutations are the source of variations and new genetic materials. These are the permanent changes in the genetic composition of the individual in the population. These can have a dominant or recessive effect on the individuals of the population.
