What is asexual reproduction?
Asexual reproduction involves a single parent, it produces genetically identical cells
2 of 17
What is sexual reproduction?
Sexual reproduction involves two parents, it produces gentically different cells

8 of 17
What is used to cut genes out of chromosomes?
Enzymes
9 of 17
Why do farmers grow geneticaly modified crops?
Higher amount of yield, so more money

Where can the donor nucleus come from in adult cell cloning?
A skin cell
13 of 17
What sort of organisms can be genetically engineered?
Both plants and animals
14 of 17
Briefly describe how plant clones can be produced using cuttings
A branch from the parent plant is cut off, its lower leaves removed and the stem planted in damp compost

Name one useful product that humans have genetically modified bacteria to produce
Insulin

Explain how a sheep can be cloned using adult cell cloning
The nucleus is removed from an unfertilised egg cell and the nucleus is removed from an adult body cell and stimulate the egg cell with an electric shock to make it divide. When its divided, you implant it into a surrogate female sheep to develope
