A gene is hereditary (gotten from mom and dad) unit consisting of a sequence of DNA that occupies a specific location on a chromosome. Mutations are changes in the DNA.
A single mutation can have a large effect and some have no effect. It depends on which base or bases have changed. If the change is in what is called a coding sequence then the result can be a different or non-functioning protein.
Sickle cell anemia and Polycystic kidney disease are examples.
Gene mutations involve changes in the DNA sequence of a specific gene, such as substitutions, insertions, or deletions, without altering the overall structure or number of chromosomes. In contrast, chromosomal mutations involve larger-scale changes, such as duplications, deletions, inversions, or translocations of entire chromosome segments. Since gene mutations occur at a smaller scale and do not affect the chromosome's integrity or arrangement, they do not lead to chromosomal mutations. Thus, while both types of mutations can impact an organism's traits, they operate at different levels of genetic organization.
Sex-linked mutations and gene mutations are alike in that both involve changes to the DNA sequence that can affect an organism's traits or functions. However, they differ in their location and inheritance patterns: sex-linked mutations occur on the sex chromosomes (X or Y), typically affecting traits associated with gender, while gene mutations can occur on any chromosome and affect a wide range of traits regardless of sex. Additionally, sex-linked mutations are often passed down differently in males and females due to their association with sex chromosomes.
Genes produce proteins that cause traits.
Gene mutations may have positive or negative effects. Without "positive" gene mutations, a species would not be able to improve itself over time, in order to make it more it more adaptable to its environment. "Negative" gene mutations, by their very nature and definition, tend not to be able to survive in their environment.
Sex-linked mutations and gene mutations both involve changes in the DNA sequence that can affect an organism's traits. They can arise from similar mechanisms, such as errors during DNA replication or environmental factors. Both types of mutations can be passed to offspring, influencing genetic diversity and inheritance patterns. Additionally, they can lead to various phenotypic effects, depending on whether they occur in coding or regulatory regions of genes.
gene mutations can affect protein production through various mutations as nonsense mutations are any genetic mutation that leads to the RNA sequence becoming a stop codon. missense mutations are mutations that changes an amino acid from one to another. Slient mutations are mutations that dont affect the protein at all.
Changes in a DNA sequence of a single gene is called a point mutation. These mutations can be harmful or not to the organism.

Mutagenic agents are substances that can cause changes in an organism's DNA, leading to mutations. These mutations can affect the way cells grow and replicate, potentially causing harmful effects such as cancer or genetic disorders.
The gene will code for a different protein than it should.
Mutation
Genes produce proteins that cause traits.
Frameshift mutations, where nucleotides are inserted or deleted from the DNA sequence, are among the most disruptive gene mutations. These mutations can alter the entire reading frame of the gene, leading to a cascade of incorrect amino acids being produced during protein synthesis. This can result in nonfunctional or severely altered proteins that can have significant impacts on an organism's ability to function properly.
Gene mutations may have positive or negative effects. Without "positive" gene mutations, a species would not be able to improve itself over time, in order to make it more it more adaptable to its environment. "Negative" gene mutations, by their very nature and definition, tend not to be able to survive in their environment.
A mutation can take effect on an organism immediately upon occurrence, influencing traits or characteristics. However, some mutations may not result in noticeable effects depending on the gene involved or if it occurs in non-coding regions of the DNA.
