1.)Mutations can be inherited. This means if a parent has a mutation in his/her DNA, then the mutation is passed on to the child.
2.)Mutations can be acquired. This happens when a mistake accurs when a cell copies its DNA.
3.)Mutations can occur by a hidden gene. This happens when your ancestor(for example, "grandma") has the mutation and that mutation is passed on to every other girl(for example), then the girl will get the mutation.

What causes mutations?
sunlight, radiation, and smoking
What causes genetic divercity in animals?
Mutations, crossing overs...
Fill in the blank Environmental causes of mutations are called?
mutagens
What are the three things biodiversity emerges from?
extinction, natural selection, and mutations
How does natural selection affect the frequency of mutatons?
Natural selection works on mutations that are already in place. The environmental changes will select for certain mutations if the selective pressure is supplied long enough for several generations of offspring to carry a higher percentage of the mutation.
What causes mutations?
sunlight, radiation, and smoking
How do natural selection cloning and selective breeding lead to evolutionary change?
The only thing that causes evolution is Mutations due to forced natural selection of desired alleles.
What are the mechanisms of evolution?
There are several mechanisms for evolution. The first (and most important) being natural selection, which plays off random mutations. Genetic drift is also another important aspect of evolution. EDIT: It depends on what you mean by "mechanism." Mutations are thought to be the mechanism that causes the change in DNA, then natural selection and Gentic drift take over. Unfortunately, mutations do not hold up and evolution is ultimately left without a mechanism. This article on mutations gives an indepth explanation http://www.answersingenesis.org/articles/wow/are-mutations-the-engine STRAIT FROM THE BIOLOGY BOOK :)
What causes mutations that ends in an n?
Radiation.
Natural selection is due to?
beneficial mutations
Which mutations are NOT subject to natural selection - lethal physiological neutral or morphological?
Neutral mutations confer no benefits or handicaps and are therefore not affected by natural selection.
Is 'mutations are beneficial to organisms' a true statement about mutations?
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
What causes variations in numbats?
Mutations in a numbat's DNA.
How does slow change over time occur genetically?
Through mutations in DNA, and natural selection of advantageous mutations.
What causes genetic divercity in animals?
Mutations, crossing overs...
Fill in the blank Environmental causes of mutations are called?
mutagens
The explanation for the diversity seen in nature is?
Natural slection acting on mutations
