Genetic Engineering SELECTIVE BREEDING…..HYBRIDIZATION…TRANSGENIC INBREEDING….CLONE….

The quiz is about a dozen questions The quiz is about a dozen questions Come in quietly, clear your desk and prepare to take the quiz.

Class definition Genetic engineering = changing or influencing the genetic makeup OR Altering GENES

GENETIC VARIETY (Sunny, Roo, James & Bear)

Different traits being expressed among the same species

SELECTIVE BREEDING DEFINITION: SELECTIVE BREEDING = METHOD OF BREEDING THAT ALLOWS ONLY THOSE INDIVIDUAL ORGANISMS W/DESIRED CHARACTERISTICS TO PRODUCE THE NEXT GENERATION  Allowing only those plants/animals that have desired traits to reproduce and thus pass on their genes to the next generation.

SOMETHING IS WRONG HERE…

Selective breeding

HYBRIDIZATION HYBRIDIZATION = BREEDING TECHNIQUE THAT INVOLVES CROSSING DISSIMILAR INDIVIDUALS TO BRING TOGETHER THE BEST TRAITS OF BOTH ORGANISMS  Choosing two desirable parents that together could potentially produce offspring that inherits ALL of the desirable traits (from both parents)

HYBRIDIZATION + =

Mutation +=

Inbreeding Inbreeding = continued breeding of individuals w/similar characteristics to maintain the desired characteristics of a line of organisms Can you think of an example from history that demonstrated the complications that result from inbreeding?

INBREEDING…?

Why is inbreeding so dangerous?

TRANSGENIC TRANSGENIC= TERM USED TO REFER TO AN ORGANISM THAT CONTAINS GENES FROM OTHER ORGANISMS  What example of a transgenic organism have your read about?  What type of transgenic organism would YOU design?

Transgenic Rabbit...can you guess which two organisms?

Transgenic Mouse..can you guess which two organisms?

#1 reason we GENETICALLY ENGINEER FOOD FOR PESTICIDES!!! (ALSO MONEY $)

CLONE A CLONE IS MEMBER OF A POPULATION OF GENTICALLY IDENTICAL CELLS PRODUCED FROM A SINGLE CELL

CLONING Have you ever wished you could have a clone of yourself to do homework while you hit the skate park or went out with your friends? Imagine if you could really do that. Where would you start? What exactly is cloning? Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the two!

CROSS BREEDING To produce (an organism) by the mating of individuals of different breeds, varieties, or species; hybridize. VERY SIMILAR TO HYBRIDIZATION

CROSS BREEDING EXAMPLE

GENETICS SCIENTIFIC STUDY OF HEREDITY / GENES

BREEDING THE ACTION OR PROCESS OF REPRODUCING/ GENERATING
