| (B) Breeding within the same breed with no common ancestor | (II) Inter-specific hybridization |
| (C) Breeding of superior male of one breed with the superior female of another breed | (III) Test-crossing |
| (D) Breeding of animals of two different but related species | (IV) Out-crossing |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
(A) Crossing tall F2 progeny with recessive parent to determine its genotype — this matches (III) Test-crossing. Crossing with the recessive parent shows whether the plant is TT or Tt.
(B) Breeding within the same breed with no common ancestor — this matches (IV) Out-crossing. Animals of the same breed with no common ancestors for 4–6 generations are mated; it helps overcome inbreeding depression.
(C) Breeding of superior male of one breed with the superior female of another breed — this matches (I) Cross-breeding. It combines the good qualities of two breeds, as in Hisardale sheep.
(D) Breeding of animals of two different but related species — this matches (II) Inter-specific hybridization. The mule is a cross of a female horse and a male donkey.
