Question 1

What can farmers to improve their livestock and the produce created?

Answer 1

do selective breeding

Question 2

What are the advantages of selective breeding? (4)

Answer 2

higher yields, products are available for longer periods of the year, extends an organisms tolerance and can produce more uniform crop (easier to harvest)

Question 3

What is genetic engineering?

Answer 3

Scientists can alter an organisms genes to produce desired characteristics. Genes are put into a plant or animal cells at an early stage of development. As it develops it will display the characteristics of the foreign gene

Question 4

Why is genetic engineering better than selective breeding for farmers?

Answer 4

because it is quicker and it can happen in one generation

Question 5

What is an example of a genetically modified product?

Answer 5

Tomato - Frost resistant
Cotton - High yield and pest resistance
