Variation or traits are due to changes in the genes. The genes are found in the DNA and when they replicate, the process doesn't always work correctly. We have called these mutations. A few are positive for the species, some are negative (and are not passed on) and a few do not make any change at all.

What happens during which mountains and variations occur?
Mountains and variations occur due to the land moving and changing gradually over time. Mountains and variations can effect the way that land sits and moves.
What are the Kinds of variation?
Variations are of following types:- 1.Somatic and Germinal Variations. 2.Continuous and Discontinuous Variations. 3.Determinate and Indeterminate Variations. 4.Meristic and Substantive Variations. 5.Other Variations.
What is somatic variation?
Mutations that occur in the somatic cells are called somatic variations .New mutations occur twice as frequently in sperm as in eggs(germ cells), probably because so many more cell divisions are required to make sperm than eggs.
What determines which variations are selected for or against?
The ability of those variations to survive and be reproductively successful against other variations in the immediate selective environment. The coin evolution pays in is reproductive success.
When the problem says write a few sentences comparing their variations what does variations mean?
you guys should figure it out

How do variations occur?
During evolution, chromosomal cariation in structure cannot occur due to
How variations occur in a population?
because the fountain is magic
Differences that occur between members of a species?
It is called variations
Large seasonal weather variations occur in what zone?
Torrid
Why variations are important in human life?
Variations are the basis of evolution, but variations within a population create diversity, which is useful to slow disease and allow natural selection to occur.
The variations needed for the origin of structural and physiological adaptations to occur are provided by what?
L
Why voltage in transformer suddenly increases and then decreases suddenly?
In perfect condition, the voltage variations does not occur.. Due to failure causes, voltage variations will arise
Which probably causes the coat color variations that occur only in the females of a certain animal?
There are a few things that might cause coat color variations that occur only in the females of a certain animal. These traits are sex-linked on the chromosomes.
What subdivision of zoology would study the DNA and variations that occur between types of lizard?
no
What are the changes when using dc voltages as modulating signal?
none, no modulation variations occur.
A key concept in the modern theory of evolution explains?
how variations occur within a species
