Genetic Engineering Flashcards
define selective breeding
the concept of choosing the best qualities/traits and breeding more
selecting for certain alleles that code for the traits we want
what are the drawbacks of selective breeding
- reduced gene pool
- best individuals are closely related (inbreeding)
- less variation within the population
what is a GMF
Genetically Modified Food
what is a GMO
Genetically Modified Organism
What are the positives GMFs
- longer shelf life
- higher nutritional value
- higher yield
- disease resistant
- drought and flood tolerant crops
What are the negatives of GMFs
- smaller gene pool
- fear of long-term consequences
- unnatural
- against your religion
What is Gene Splicing?
using recombinant DNA
* cutting out plasmids (small DNA strand) found in bacteria and inserting it into humans
* insulin production increased
How is genetic engineering used to produce
vaccines?
GENE THERAPY:
* using recombinant DNA from gene splicing
* produced insulin vaccines
define environmental factor
any non-genetic factor that influences the phenotype of an individual (eg. exposure to pollution, temperature, diet)
What issues do Genetically Modified Crops bring
- farmers use pesticides
- farmers weed killers
- invasive
- threat to produced crops
What are the benefits Golden Rice?
- a staple in many countries (eg. Philippines)
- added source of Vitamin A (contains Beta Carotine)
- increased yield
- drought and flood resistant
- prevents blindness
