- cloning
- plants
- tissue culture
- where a few plant cells are put in a growth medium with plant hormones.
- this creates a clone of the first plant
- can be grown quickly
- not a lot of space needed
- can be grown all year
- used by scientists to preserve rare plants that don't reproduce often enough.
- where a few plant cells are put in a growth medium with plant hormones.
- cuttings
- cuttings can be taken from a good parent plant and ten it can be planted to make a genetically identical plant
- simpler than tissue culture
- quick and cheap
- tissue culture
- animal cloning
- adult cell cloning
- this involves taking an unfertilized egg celland removing its nucleus
- then an adult body cell nucleus is taken and is inserted into the empty egg cell.
- this egg cell is then stimulated by shocking it to make it divide
- when the embryo is a ball of cells it is then inserted into an adult females womb
- this egg cell is then stimulated by shocking it to make it divide
- then an adult body cell nucleus is taken and is inserted into the empty egg cell.
- this involves taking an unfertilized egg celland removing its nucleus
- controversies
- the gene pool reduces over time so the alleles are lost
- if a new disease appears then all of the cloned organisms will be wiped out
- the offspring has a chance of being unhealthy
- pro's
- it can help scientists understand the embryo nd age related disorders
- can help preserve endangered species
- adult cell cloning
- plants
