Question

How is gene flow different from a mutation?

Answer 1

Gene flow and Migration

1. Gene flow or gene migration is the movement of genes from one population to another.
2. A mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.

Gene flow	Mutation
1.Gene flow is the migration of genes from one population to another and causes variation in that population.	1. Changes undergone in the base-pair sequence of the DNA are called mutations
2. This variable flow of individuals in and out of the population not only changes the gene structure of the population, but can also introduce new genetic variation to populations in different geological locations and habitats.	2. Mutation causes changes in the sequence of nucleotides in DNA of an individual and creates variations within a population.
3.It can be caused due to migration of individual organisms that reproduce in their new populations, or due to the movement of gametes	3. It can be caused due to UV or ionizing radiation, chemicals, or viruses.
