EXAMPLES: Goats, Giraffes Farmers want to improve quality and quantity.
EXAMPLES: Cows, wolves, crops. Selective Breeding with Plants * Farmers Take the Largest of a Kind and replant it.
* Mixing/ Mating Two Different Strands
* Controlling Ethylene
* Other Hormones: Gibberellins
- Grapes Diploid-An organism or cell that has double the basic single number of chromosomes.
Triploid-An organism or cell that has triple the basic single number of chromosomes.
Tetraploid-An organism or cell that has quadruple the basic single number of chromosomes.
Cross Pollinating-The genetic exchange of information in two different plants to reproduce more members of the same species, or a cross of the two.
Global Warming-is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth.
Gibberellins-Are plant hormones that regulate growth and influence various developmental processes.
Ethylene-is a hydrocarbon and is also an important natural plant hormone, used in agriculture to force the ripening of fruits. Glossary: PROS & CONS *Betters animals and plants.
*Food and buisness improves.
*Rules out use of steroids.
