Genetic Adaptation

In biological theory of genetic evolution adaptation refers to psychological or behavioural changes which result in increased chances of survival in a given environment.The genetic quality of the human race can be improved through positive eugenics involving reproduction among those considered by society as desirable and by negative eugenics involving discouragement of reproduction among those with genetic defects.


Genetic counselling helps people to get necessary genetic and medical information along with information on social,economic and psychological aspects.Genetic screening can help the future generation to get rid of many undesirable inherited diseases.Screening may be done in the prenatal stage.Many chromosomal abnormalities can be detected at prenatal stage.Avoidance of marriage help in elimination of diseases related to recessive genes.In the transformation technique introduction of genetic information from external sources is involved.DNA technology has helped in correcting defects in man.
