Mastery of Selective Breeding

What is the primary objective of selective breeding in farming?

• To make plants and animals more resistant to diseases

• To enhance genetic variety in crops and livestock

• To generate offspring with certain favorable characteristics

• To let nature determine the most suitable traits for survival

What is the main difference between artificial selection and evolution?

• Artificial selection is a natural process, while evolution is man-made

• Evolution is a natural process, while artificial selection is man-made

• There is no difference; both terms mean the same thing

• Artificial selection involves chemicals, while evolution does not

What is the primary reason for a breeder to use cross-breeding in selective breeding programs?

• To reduce the size of the population

• To eliminate all traits from a population

• To introduce new, desirable traits into a population

• To help the population adapt to old environments

What is the main difference between genetic engineering and traditional breeding methods?

• Traditional breeding methods can only be applied to animals, while genetic engineering is applicable to plants

• Traditional breeding methods involve selecting parents with desired traits, whereas genetic engineering involves altering genes directly

• Genetic engineering is a natural process, while traditional breeding methods are not

• There is no difference; both methods result in genetically identical organisms

Which of the following characteristics is often enhanced in plants through selective breeding?

• Increased vulnerability to diseases

• Reduced crop yield

• Improved resistance to pests

• Decreased lifespan

What is the process called when two different species are crossed to produce a hybrid?

• Mutation

• Hybridization

• Cloning

• Inbreeding

Who is the scientist that discovered the fundamental laws of inheritance, which are crucial for understanding genetic inheritance and selective breeding?

• Albert Einstein

• Gregor Mendel

• Marie Curie

• Galileo Galilei

What is the term for the process of selecting parents with desirable traits to breed in hopes of passing those traits onto the offspring?

• Artificial selection

• Natural selection

• Genetic modification

• Hybridization
