Is Receiving different genes from each parent Genetic variation ?

Dear user,

Answer to your query is provided below

Genetic variations can be defined as the changes in the genetic material or in the alleles of the genes of a population. Variations which are beneficial for the population and help in the better survival of the population are naturally selected. Accumulation of many such variations result in development of new species. Variation is the raw material for evolution.

For example: Let us suppose that a population of bird with long beaks inhabit a new area. In that area, they have food which can be consumed properly with short beaks. Due to certain variations, there are some birds with short beaks in that population. So, in the new area they will survive better and reproduce more, hence there number will increase and slowly they will evolve into a new species.

Explanation:

Processes that lead to genetic variation in the progeny are as follows:

Mutation

Genetic recombination during sexual reproduction.

Gene flow i.e movement of genes from one population to other.
