Can traits of organisms always be predicted with selective breeding? Explain how multiple causes can influence the traits of an organism.

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.

while it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for slaves to grow and pick the cotton.

explanation:

before eli whitney's invention of the cotton gin, picking and cleaning cotton was a slow, labor-intensive job. workers, usually slaves, had to pick the seeds from the cotton fibers by hand. this invention made it possible to grow large amounts of cotton on big farms and make money.
