discuss the potential impact of the use of reproduction technologies on genetic diversity of species using a named plant and animal example that have been genetically altered
- Reproductive technologies, such as cloning, and the engineering of transgenic species have the potential to both increase and decrease genetic diversity. By moving genes from species to species, the genetic diversity is being increased. Crops, such as rice, have been genetically engineered to suit a particular climate and topography, making then resistant to herbicides and pesticides commonly used in a particular region.
- Transgenic animals present greater problems with lower success rates so far. One important use is seen to be the preservation of numbers of endangered species. The first cloned endangered mammal was a guar (an endangered wild ox from SE Asia), but unfortunately it did not survive. It is hoped that reproductive technologies such as cloning and sperm and embryo banks can be used to preserve stocks of threatened species.
