1. Key Ideas

Modern agriculture does not simply wait for reproduction to happen. Farmers and breeders deliberately control which plants are pollinated, which animals mate, when semen is used, and even which embryos are transferred. These choices can increase productivity, but they also create biological and ethical trade-offs.

How selective breeding manipulates inherited traits.
Why agriculture benefits from greater productivity, uniformity and sometimes disease resistance.

2. Success Criteria

By the end, you should be able to:

How selective breeding manipulates inherited traits.
How artificial insemination, controlled mating and embryo transfer are used in animals.
How controlled pollination is used in plant breeding.

3. Key Terms

Selective breedingChoosing parents with desirable characteristics so those traits are more likely to appear in offspring.

Artificial inseminationIntroducing semen into the female reproductive tract without natural mating.

Controlled matingManaging which animals reproduce together to influence inherited traits.

Controlled pollinationDeliberately transferring pollen between selected plants to control inheritance.

Embryo transferPlacing an embryo from one female into another female for development.

Gene poolThe total variety of alleles present in a population.
