Which of the following is INCORRECT regarding inbreeding?
Show Hint
Inbreeding is mating of closely related animals of the same breed.
Updated On: Nov 12, 2026
- By inbreeding, pure lines of animals can be obtained.
- It involves breeding of animals of two related species having no common ancestors.
- It is useful in the elimination of harmful recessive genes.
- It is useful for accumulation of superior genes.
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Inbreeding is mating between closely related animals of the same breed, usually for 4 to 6 generations.
Step 2: Check the statements
It increases homozygosity, so pure lines can be obtained. It exposes harmful recessive genes so they can be removed. It also helps to accumulate superior genes.
Step 3: Find the wrong one
Breeding animals of two related species with no common ancestor is outbreeding or interspecific hybridisation, not inbreeding.
Final Answer:
The statement about breeding two different species with no common ancestor is incorrect. \[ \boxed{\text{(B) }\text{It involves breeding of animals of two related species having no common ancestors.}} \]
