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

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 combinati

How is variation causes?

There are several causes for variation that occur within apopulation. Some of these causes include neutral mutations, sexualreproduction, 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 can cause variation?

Cross pollination, mutation and polyploidy lead to variations in the progeny

What is variation caused by?

It is caused by crossing over in sexual reproduction and random mutations in DNA.

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 variation among human or other living organisms?

the variations in genes, genes of sexually reproducing organisms will vary due to crossing-over of genes, mutations, and adaptations. In asexually reproducing organisms genes

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

What kind of reproduction causes variation in organisms?

Sexual reproduction causes most variation in organisms. This isbecause genes get mixed up in the process whereas in asexualreproduction the offspring is genetically identical
