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.
Are mutations a significant source of genetic variation?
Yes, mutations are a significant source of genetic variation as they introduce new genetic changes that can lead to differences in traits among individuals within a population.
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.
Are the body's primary and immediate source of energy?
Carbohydrates are the body's primary and immediate source of energy.
What is the primary source of energy used to form an ATP molecule?
The primary source of energy used to form an ATP molecule is the breakdown of glucose through cellular respiration.
What are the sources of genetic variation in bacteria and humans?
The most important source of variability in bacteria is mutation.
Why do prokaryotes and eukaryotes differ in there reliance on mutations for generating genetic variations?
Prokaryotes rely more on mutations for generating genetic variations because they reproduce asexually, so mutations are a primary source of genetic diversity. Eukaryotes reproduce sexually, which introduces genetic variations through meiosis and recombination, reducing the reliance on mutations for generating diversity.

What is the primary original source of genetic variation in a population?
The primary original source of genetic variation in a population is mutation. Mutations are changes in the DNA sequence that can lead to new genetic variations in populations, providing the raw material for evolution to occur.
Was hybridization the ultimate source of genetic variability?
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.
Is a diary primary or secondary?
It is a primary source.
Is this a primary or a secondary source?
This is a primary source.
Is a picture a primary or secondary source?
A picture can indeed be a primary source.
Is the Rosetta stone secondary or primary source?
it is a primary source
Could a photograph be considered a primary source Why or why not?
It is a primary source because it was taken at the time.
What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
Is the Mayflower Compact a primary or secondary source?
Primary Source
