Often in reproduction, broken chromosomes are formed by random natural factors.
When these combine with other chromosomes, new characteristics can be formed which are different from the Natural Chromosomes.

What is the ultimate source of genetic variation and the basis for the diversity of life on earth?
Mutations. These have quite a few different causes. Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.
What is the ultimate source of genetic variablility in dna?

What is the ultimate source of genetic variation and the bases for the diversity of life on earth?

What is the ultimate source of variation needed for evolutionary change?
mutation
What process provides the genetic variability that natural selection acts on during evolution?
The ultimate source of variation is mutation. However, recombination, or crossing over, can produce enormous amounts of variation by shuffling alleles into different combinations. Combined, the two processes produce the variation upon which natural selection can act, and which results in evolution.
What are the sources of genetic variation in bacteria and humans?
The most important source of variability in bacteria is mutation.
What are three ways to get genetic variation?
Independent assortment of chromosomes, crossing over and Random fetiliztion
How can you show that plants are the ultimate source of energy?
plants are not the ultimate source of energy. It is the sun which is the ultimate source of energy to this planet
What mutation can be source of genetic?
the mutation can be a sources of genetic variety.
What is the primary source of genetic variability in prokaryotes?
Both of the following are correct: They have extremely short generation times and large populations; They can exchange DNA with many types of prokaryotes by way of horizontal gene transfer.
