Class definitionClass definition

Genetic engineering = changing or influencing the genetic makeup

OR Altering GENES

GENETIC VARIETY (Sunny, Roo, GENETIC VARIETY (Sunny, Roo, James & Bear)James & Bear)

Different traits being expressed among the same species

SELECTIVE BREEDINGSELECTIVE 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…SOMETHING IS WRONG HERE…

Selective breedingSelective breeding

HYBRIDIZATIONHYBRIDIZATION

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)

InbreedingInbreeding

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…?INBREEDING…?

Why is inbreeding so dangerous?

TRANSGENICTRANSGENIC

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

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

CLONECLONE

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

CLONINGCLONING

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 BREEDINGCROSS BREEDING

 To produce (an organism) by the mating of individuals of different breeds, varieties, or species; hybridize.
