PRACTICAL APPLICATIONS OF GENETICS

PRACTICAL APPLICATIONS OF GENETICS.
Study of genetics has been put into a wide variety of uses encompassing plants and animals and in particular humans. Blood transfusion
Blood groups are genetically determined.
As discussed earlier a person of blood group A can only get blood from another one of A or O.
In case of emergencies and unavailability of blood, a patient may be given blood group A + when he/she is A-.
First transfusion is fine since, by the time enough antibodies are produced most of the red blood cells of donor have completed their lifespan but a subsequent transfusion of A+ blood is fatal.
