The differences shown by the individuals of one kind of organisms are called variations. Variations are due to hereditary and non-hereditary characteristics. Characteristics, which are passed from parents to off spring, are called hereditary characteristics.
In general the term variation means the difference in characteristics of organisms belonging to the same species in a natural population.
Two types of variation, i.e. continuous and discontinuous, occur in any large population. In continuous variation, there are small differences among individuals of the same species and many intermediate forms are seen. So there is a complete gradation of many characteristics of organisms from one extreme to the other in a population. E.g. height in human being. Characteristics showing continuous variation are produced due to combined effects of many genes and environmental factors.

What are variation?
gray wolves variation trait
What is the slight difference among objects or organisms that are the same basic type?
VARIATION
Is genetic variation found only in wild organisms in nature?
No.
What is essnetial to evolution?
Genetic and morphological variation. Without variation in organisms there would only be the shifts of genetic drift and gene flow in organisms. When organusms are varied then one can be selected from the other by the environment and the organisms ability to reproduce against that environment. Then there is evolution.
Mendel principles account for genetic variation in organisms?
True yes
Which is a source of genetic variation in sexually-reproducting organisms?
Basic source of variation in all organisms is mutation .
What is the study of genetics?
The science of genes, heredity, and the variation of organisms.
What are the two types of variation shown by living organisms?
nonsense ,dum and crazy are the two types variation shown by living organisms.
What is the importance of variation in organism?
Variation is important among organisms for us to indicate which is which :))
What are variation?
gray wolves variation trait
What are the islands where Charles Darwin observed variation among organisms?
Galapagos Islands are the islands where Charles Darwin observed variation among organisms.
What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
What is the slight difference among objects or organisms that are the same basic type?
VARIATION
Why is crossing over so important?
It increases genetic variation in organisms
Why all organisms show variation?
Variations arise due to recombinations(gene rearrangements) ,mutations etc.The former is the principal source of variation in sexually reproducing organisms and the latter is the source of variation in asexual organisms.According to Darwin variation arises due to chance since all the above mentioned process occur in nature spontanuously all organisms show variation
Molecules responsible for hereditary and variation of organisms?
DNA is responsible in most organisms, but RNA is responsible for heredity and variation of a lot of viruses.
Is genetic variation found only in wild organisms in nature?
No.
