Advances In Genetics

Learning Objectives


Describe
3
ways of producing organisms with
desired traits.



Recognize and explore the impact of
biotechnology on individuals, society, and the
enviroment.

How Can Organisms Be Produced With Desired Traits?

How Can
Organisms
With Desired
Traits Be
Produced?



Cloning


Genetic Engineering


Artificial Selection


Cloning

Clone



Organism that has exactly the
same genes of organism from which
produces


Example: Cut stem of plant and put
in water

Genetic Engineering

Genetic
Engineering






Gene Therapy



Genes from 1 organism are
transferred in DNA of another
organism


Causes organisms to develop
desired traits


May have long term side effects



Inserting copies of genes into a
person’s cells

Artificial Selection

Selective
Breeding


Hybridization



Inbreeding


Artificially selecting organisms with
desired traits to be parents



Breeders cross
2
genetically
different individuals



Crossing
2
individuals that have
similar desirable traits

What Is The Impact Of Biotechnology?

Biotechnology





Impact on
Individuals



Application of technological
process, invention, or method to
living organisms


Many benefits, but also risks



Can learn about and develop
treatments for diseases


Can predict chances of developing
diseases

What Is The Impact Of Biotechnology?

Impact on
Society




Impact on
Environment



Creates jobs, cheaper
medicines/crops, and improved
quality of life




Can improve living conditions


Can cause unintended harm to
other species
