- Cloning
- cloning plants
- cuttings- cutting taken (eg from a branch) and dipped in rooting hormone. Pot is covered with a bag to keep it warm and moist so it does not wilt and grows well
- Tissue Culture- tissue sample scraped from plant, placed in Agar growth medium cointaining nutrients and auxins. After the start to develop into tiny planllets they're planted in compost
- advantages
- done quickly
- preserve endangered spieces
- creates ideal offspring
- cheaper
- tissue culture can be done all year round, more created from one plant and guaranteed growth
- the study of cloned animals could lead to greater understanding of the development of the embryo, aging and aging related disorder
- disadvantages
- reduced gene pool, can be wiped out by new disease
- change in environment (drought etc) can wipe out all clones
- if parent plant is not perfect faults can be passed on
- Cloning animals
- Embryo Transplants
- 1. sperm cells from best bull, egg cells from best cow
- 2. sperm artificially fertilises egg cell, embryo develops and splits (to form clones)
- 3. cloned embryos implanted in host mothers who have been given hormones to get them ready for pregnancy
- 2. sperm artificially fertilises egg cell, embryo develops and splits (to form clones)
- 1. sperm cells from best bull, egg cells from best cow
- Adult cell cloning
- 1. take an unfertilised egg cell, remove nucleus
- 2. nucleus from an udder cell from a donor sheep after a mild electric shock, it's inserted into the empty egg cell
- 3. this makes it divide just like a normal embryo.
- 4. when the embryo is a ball of cells it is implanted into a female
- 3. this makes it divide just like a normal embryo.
