why is wheat breeding done
meet future demands of the world population
how do scientists identify genes that improve e.g. rust resistance in wheat
use PCR and gel electrophoresis to reveal PCR markers
What can DNA identification technologies used for
accurately trace the genetics of desirable traits and to acquire this traits within a generation
What are genome map used for
identify genes and regulatory elements underlying complex agronomic traits
Agronomic
pertaining to plant physiology
Examples of agronomic traits
yield, grain quality, resistance to fungal diseases and tolerance to abiotic stress
How is Identification technologies used in pork industry
select pigs with the most desirable traits for breeding
Desirable traits in pigs include
increased litter size and growth rate, and improved carcase quality (e.g. taste and tenderness)
How do scientists modify
molecular tolls and techniques
What are the effect of modifying food crops
increases their nutritional value and crop yield
What has biotechnology applied to?
reducing the impacts of pests on crops
What is the effect of reducing the impacts of pests on crops?
increasing the amount of food available in developing countries
Describe the process used for transformation
gene is taken from one species and inserting it into another to obtain a desired characteristic
What is the technology for the process of transformation known as
Recombinant DNA technology
What are cotton plants susceptible to
cotton bollworm, caused by moths
How is biotechnology applied to the cotton plants
genes from the bacterium are inserted into cotton plants to protect from damage from insects
What are the effects of genetically engineered cotton
reduce the use of insecticides, cutting farmer costs
What is transgenic Atlantic salmon known as
Aqua-Advantage Salmon
How is Aqua-Advantage Salmon different from normal fish
capable of growing at a double the rate of conventional Atlantic Salmon
What are some abiotifc factors that affect crops
extreme temperatures, drought, high salinity, deficient soil nutrients and flooding
Example of transgenic organism for nutrition
