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.
There are several causes for variation that occur within a population. Some of these causes include neutral mutations, sexual reproduction, and diploidy.
variation are caused by meiosis as they split and swap bits of chromosomes to the daughter cells to create variation
Cross pollination, mutation and polyploidy lead to variations in the progeny
Mutations and sexual reproduction
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.
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.
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.
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.
you guys should figure it out

During evolution, chromosomal cariation in structure cannot occur due to
because the fountain is magic
Torrid
It is called variations
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.
L
In perfect condition, the voltage variations does not occur.. Due to failure causes, voltage variations will arise
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.
no
none, no modulation variations occur.
