What are potential pros and cons of having such tests done and of referring to dna sequences when determining a patient’s medical treatment?

DNA mapping has several characteristics that define the positive and negative points of its use in any patient. As a pro, we can mention that through it you can detect genetic and hereditary diseases by analyzing modified genes, and discover a disease and treat it even before it develops. The cons is that DNA mapping is still linked to ethical and social issues that may go beyond accepted societal limits and possible by current medicine, for example a patient who discovers a predisposition to a serious illness while young and develops psychological disorders due to this. discovery, even before it occurs.

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.
