This question tests knowledge across various biological concepts including genetics, molecular biology, and agricultural science. The key is to identify the correct association for each term. For instance, Eco R1 is a well-known restriction enzyme, Teosinte is the wild ancestor of maize, and ABO blood groups are a classic example of multiple alleles. Gene ala 3 is known for its role in antifreeze proteins. Antibiosis refers to the inhibition of one organism by another, often seen in insect resistance mechanisms. Linkage drag is a consequence of distant hybridization where undesirable genes are carried along with desirable ones. Isolation distance is a crucial factor in maintaining the genetic purity of seeds.
Match the List – I with List – II and select the correct answer by using the codes given below the lists : List – I 1. Gene ala 3 2. Antibiosis 3. Teosinte 4. Linkage drag 5. Isolation distance 6. ABO blood group 7. Eco R1 Codes : (1) A B C D E F G (2) E F G D (3) G F E D (4) C F E D List – II A. seed production B. multiple alleles C. antifreeze D. distant hybridization E. maize F. insect resistance G. restriction enzyme
