Answer:
Selective breeding involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics.
Humans have selectively bred plants and animals for thousands of years including:
crop plants with better yields
ornamental plants with particular flower shapes and colours
farm animals that produce more, better quality meat or wool
dogs with particular physiques and temperaments, suited to do jobs like herd sheep or collect pheasants.
Selective breeding aims to adapt an organism’s characteristics in a way that is desirable to the humans that breed them.
The traits of organisms can always be predicted with selective breeding and this can be influenced through the genes of the parents or the environment.
- Selective breeding simply means selecting a parent that has some certain characteristics which is vital so that they can breed together and give birth to offsprings which have the same characteristics.
- A trait refers to the characteristics that a particular organism has. It should be noted that the trait of an organism can be denoted by the genes of one's parents or the environment. Offsprings usually have some characters that their parents possess as well.
- For example, a father can choose the plants that will help produce more grains, cows that will produce more milk, hens they will lay more eggs, etc.
