GENETIC CHANGES CAUSED BY HUMANS
Selective breeding: Cross organisms with traits you like to get offspring with desired traits
Selective breeding: Humans have been breeding organisms for desired traits for THOUSANDS of years
Selective breeding: Hybridization: Cross organisms with two different good traits to get BOTH traits
Selective breeding: Inbreeding: Cross individuals with similar traits to keep traits pure
Genetic Engineering: Transferring genes from one organism into the chromosomes of another to get NEW traits
GENETIC ENGINEERING USES SINGLE CELLS! Later, the cell splits and forms more cells or a whole organism.
There are several concerns There are several concerns. Many people feel very strongly about genetic engineering.
Still, genetically engineered crops are very common:
