Question

The following table describes some biotechnological processes.

Biotechnological Processes
Process Description
1 Cross-breeding a high-yielding wheat variety with a disease-resistant wheat variety
2 Inserting bacterial toxin production genes in cotton


Which biotechnological processes are described in the table? (3 points)

Both processes describe cloning.

Both processes describe genetic engineering.

Process 1 describes artificial selection and process 2 describes cloning.

Process 1 describes artificial selection and process 2 describes genetic engineering.

Answer 1

Process 1 describes artificial selection (selective cross-breeding) and Process 2 describes genetic engineering.

Explanation: crossing two wheat varieties is conventional breeding/selective/artificial selection. Inserting bacterial toxin genes into cotton is genetic engineering (making a transgenic plant), not cloning.
