15.1 Selective Breeding Flashcards
Selective breeding
Only allowing certain organisms with wanted characteristics to produce the next generation
Takes advantage of naturally occurring genetic variation
Selective breeding is also known as
Artificial selection
What are the two ways that selective breeding can be done
Hybridization and inbreeding 
Hybridization
 crossing dis similar individuals to bring together the best of both organisms
Hybrids
Individuals produced by hybridization often more robust than either parents
What is an example of hybridization
Disease resistance plant x Food producing plant = plants that increase food production
Inbreeding
The continued reading of individuals of similar characteristics to maintain desirable characteristics in a line of organisms
Why is inbreeding risky
Because they are genetically similar which might bring out a recessive disorder
How do dogs keep their breed
Through inbreeding
How do breeders increase genetic variation in a population
By introducing mutations
Bio technology
Application of a technological process invention or message to living organisms
Manipulation of organisms/life for human needs 
What is one form of biotechnology important in agriculture and medicine
 selective breeding
What are some examples of biotechnology
Goat producing silk
Oil bacteria
Mutations
Irritable changes in DNA which occur spontaneously
Can mutations be increased by breeders
Yes
