Causes of variation is random mutation. Random mutationsconstantly occur in the genomes of organisms; these mutationscreate genetic variation. If all living things were same, we willall use up one type of food as our nutrient source and eventuallywe will run out of food to consume.. making less likely for us tosurvive..

Describe the process that acts on organisms to cause variation and evolution?

  The ultimate source of variation is mutation. However, recombination, or crossing over, can produce enormous amounts of variation by shuffling alleles into different com

How is variation causes?

There are several causes for variation that occur within a  population. Some of these causes include neutral mutations, sexual  reproduction, and diploidy.

Variations are caused by?

variation are caused by meiosis as they split and swap bits of chromosomes to the daughter cells to create variation

What are some causes of genetic variation in sexually reproducing organisms?

Aside from mutation the sexually reproducing variation is due to independent orientation of chromosomes in meiosis ( two ways the sister chromatids can line up in their tetrad

What causes DNA variation in organisms?

Mutation of the genetic code causes DNA variation in organisms. For example, during DNA replication, one nitrogen base may be substituted for another, or an extra base can be

What are variations what causes them?

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 mu
