point mutation, insertion and deletion
Gene rearrangement actually means the rearrangement of gene in chromosomes. This can occur through 3 different ways which are inversion, translocation and transposition. These can definitely alter the chromosome and cause mutations to occur.

Three ways mutations can occur in genes are: 1. Insertion: Extra DNA nucleoties are added to the DNA strand. 2. Deletion: DNA nucleotides are deleted, therefore, changing the DNA sequence. 3. Translocation: parts of chromosomes are exchanged.
Several different mutations can cause the same genetic disease due to the redundancy and complexity of genetic coding. Multiple mutations can occur in the same gene, affecting its function in various ways, such as altering protein structure, disrupting regulation, or leading to premature stop signals. Additionally, mutations in different genes that interact within the same biological pathway can also result in similar disease phenotypes. This genetic variability highlights the diverse mechanisms through which diseases can manifest despite differing underlying mutations.
Variations occur due to mutations. There are three factors of mutations which impact the formation of new genotypes. 1) Point Mutations - Very small impact mutation which still might enhance the protection against environment and reproduction. 2) Mutations that alter Gene number and sequence - has major role in evolution as it might help to add new functions. 3) Mutation Rates - In animals and plants mostly very slow, however, prokaryotes due to high rate are able to mutate very fast.

There are on the chromosomes stretches of DNA that do nothing. Their only purpose is provide matching stretches so the chromosomes match-up during fertilization. In here mutations occur but have no 'large' effect on the phenotype of the life-form. (If enough of them occur then the chromosome become of a different length and certain mating pairs can no longer match-up, but that takes a while to get a difference in length that really matters.) Geneticists use these stretches and the changes in them to track evolutionary path-ways.
Genetic variation, caused by mutations in DNA, is a major source of variation within species. Mutations can lead to differences in traits such as color, size, and behavior, allowing for natural selection to act upon these variations.

There are many ways that the final product is checked. Somewhat like an editor. Many mutations are lethal and some cause diseases. The last is not passed on.
Mutations in bacteria that confer antibiotic resistance help the bacteria survive and thrive in their environment, but can be harmful to humans if these bacteria cause infections that are difficult to treat. Similarly, mutations in insects that confer resistance to pesticides help them survive, but can be harmful to humans as it makes pest control more difficult.
