A Coggle Diagram about Mutations
(Example of mutations in humans are the sickle-cell disease and the Turner syndrome.
, It means the action or process of mutating. Some examples are sickle cell anemia is caused by a substitution in the beta-hemoglobin gene, which alters a single amino acid in the protein produced. change a codon to one that encodes the same amino acid and causes no change in the protein produced.

and Mutations are the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
), Genetic Variation
(Genetic Variation means a term used to describe the variation in the DNA sequence in each of our genomes. For example, population with many different alleles at a single chromosome locus has a high amount of genetic variation.

), Genetic drift
(Genetic drift — along with natural selection, mutation, and migration — is one of the basic mechanisms of evolution.In each generation, some individuals may, just by chance, leave behind a few more descendents (and genes, of course!) than other individuals. The genes of the next generation will be the genes of the "lucky" individuals, not necessarily the healthier or "better" individuals. That, in a nutshell, is genetic drift. It happens to ALL populations — there's no avoiding the vagaries of chance.
, variation in the relative frequency of different genotypes in a small population
and variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce
), Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.
(Coevolution is used to describe cases where two (or more) species reciprocally affect each other's evolution.
, An example of coevolution is when a predator affects the prey's evolution.
and Co-evolution occurs when two or more organisms evolve together.
), Evolution is when a species changes over time due to its environment or other factors.
