What is the breeding technique called when a human selects which male and female animals will mate?

• A. Selective breeding
• B. Natural selection
• C. Hybridization
• D. Linebreeding

Answer: (A)

Selecting which male and female animals will mate is selective breeding, also known as artificial selection. It’s a deliberate practice where humans evaluate traits and pair individuals whose genetics are expected to produce offspring with desirable characteristics, such as better growth, milk yield, or temperament. This human-directed pairing drives the genetic makeup of future generations and distinguishes it from natural selection, where environmental factors determine which animals reproduce without human intervention. Hybridization involves crossing different species or varieties to create new combinations, not just choosing mates within a species. Linebreeding focuses on mating related individuals to concentrate specific traits within a lineage, a more specific breeding approach rather than the general act of selecting mates for improvement.
