Genetic Engineering/Recombination

What is inbreeding?

• breeding an organism with a known genotype with an unknown genotype and using the offspring to determine the unknown.

• Breeding 2 closely related organisms.

• Breeding organisms to create hybrids.

• A process of selecting desired traits to be passed on to offspring.

Which of the following is a disadvantage of inbreeding?

• Desired traits are passed on to offspring

• Harmful recessive traits can be passed on

• Undesired traits are not passed on

• It's time consuming and expensive

What is a benefit of selective breeding?

• Gets desired traits from parents

• Gets rid of undesired traits

• Allows harmful recessive traits to be passed down.

• Takes a lot of time and is expensive.

What is selective breeding?

• breeding an organism with a known genotype with an unknown genotype and using the offspring to determine the unknown.

• Breeding 2 closely related organisms.

• Breeding organisms to create hybrids.

• A process of selecting desired traits to be passed on to offspring.

What is polyploidy?

• The combination of genes produced by crossing over and independent assortment.

• When genes located close to each other on the same chromosome tend to travel together during meiosis.

• A map that shows the sequence of genes on a chromosome.

• The occurrence of one or more extra sets of chromosomes.

What seperates DNA Fragments

• Gel Electrophoresis

• Genes

• Cells

• Restriction Enzymes

What is recombinant DNA?

• Adding DNA from one organism into the DNA of another
• DNA which has been changed over generations by natural selection
• DNA that causes genetic disorders
• DNA that has been sequenced

Which of the following is an argument in favor of Genetically modifying organisms (GMOs)

• Reduced biodiversity
• Disease resistant crops
• Food with extra nutrients
• Controlled production of insulin
