Both assertion and reason are true, and the reason is the correct explanation of the assertion.
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
The assertion is true, but the reason is false.
The assertion is false, but the reason is true.
The assertion states that inbreeding aims at increasing the yield of animals and improving their desirable qualities. This is true because inbreeding is a selective breeding technique that involves mating closely related individuals with desirable traits to concentrate those traits in the population.
The reason states that inbreeding always leads to inbreeding depression in animals. This is not the correct explanation of the assertion. While inbreeding can lead to inbreeding depression, which is the loss of fitness and the expression of harmful recessive traits, it is not always the case. Inbreeding can also result in the fixation and intensification of desired traits, leading to increased yield and improved qualities in animals.
Option 2 is the correct answer.
