Genetic modification may be defined as the change in the genetic constitution of the organism. The transgenic organism are also produced by modifying the genes.

Genetic modification of fruits and vegetables are used to increase the quality and quantity. The genetic modification increases the ability to tolerates the wide range of temperature and climatic conditions. The improvement of the important vitamins, minerals and other biological compound can be done by modifying the genome of the fruits and vegetables.

Answer from: Quest

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
