Advances in Genetics
Objective
I will identify different techniques used in advanced genetics.
Key Terms
● Selective breeding ● inbreeding ● hybridization ● clone ● genetic engineering ● gene therapy ● The Human Genome Project ● Genome
Warm Up
Dachshunds are selectively bred to fit into badger holes. What do you think the difference between selective breeding and natural selection is?
What is Selective Breeding? ● The process of selecting
organisms with desired traits to be parents of next generation - two techniques ○ Inbreeding - involves crossing two
individuals that make similar characteristics
○ Hybridization - breeders cross two
genetically different individuals in
hopes of offspring having best traits from both parents
What about clones?
● A clone is an organism that has exactly the same genes as the organism from which it was produced.
Working with Genes ● Genetic Engineering
○ Genes from one organism are transferred into the DNA of another organism (ex. bacteria producing insulin or cows producing milk with blood-clotting protein for hemophiliacs)
● Gene Therapy involves inserting copies of a gene directly into a person's cell
The Human Genome Project
● Project to identify the DNA sequence of every gene in the human genome ○ A genome is all the DNA
is one cell of an organism
Tastization
Objective:
I will create an advertisement for Tastization (the company that deal in the hybrization of great tastes).
The Project
