Question

What strategy would you suggest if a person wants to evolve a pure line in an animal?

• A. Cross-breeding
• B. Inbreeding
• C. Out-breeding
• D. Artificial insemination

Answer 1

The correct option is B Inbreeding

Pure line means to evolve an organism with the pure characters (own characters) that are passed in the future generation.

• Cross breeding is breeding between two organisms of different breed.
• Inbreeding is the cross between same species, having same characters. Inbreeding increases homozygosity and thus, is necessary for evolving a pure line in any animal.
• Out breeding is the cross between species to produce organisms whose characters would be genetically related.
• Artificial insemination is artificially injecting the species characters.

So, the correct option is 'B'.
