Advanced Production: Selective Breeding

Where humans choose which individuals of a population mate so that, over generations, all individuals offspring have only the traits that humans prefer

• Selective breeding (also known as artificial selection)

• Gene Therapy

• Gene Splicing (production of Transgenic / Genetically Modified Organisms)

• Cloning

Farmers identified characteristics in wild plants that they wanted to keep and planted seeds from those plants, gradually emphasizing certain traits and producing various crops with the biggest, tastiest traits

• Selective breeding (also known as artificial selection)

• Gene Therapy

• Gene Splicing (production of Transgenic / Genetically Modified Organisms)

• Cloning

Which is a goal of selective breeding?

SELECT ALL THAT APPLY

• To increase the value of species to humans

• To produce species that resist disease

• To produce species with desired traits

• To make specific changes to the DNA code.

The purpose of selective breeding is to

• get bigger animals

• get smaller animals

• create animals with desired traits

• create animals with bad traits

• Different types of dirt helped the plant grow differently.

• Humans chose mustard plants with certain traits to breed together.
