Chapter 9 - Biotechnology

Which of the following have been produced by selective breeding?

• horse breeds

• cat breeds

• dog breeds

• all of the above

Selective breeding produces

• more offspring

• fewer offspring

• desired traits in offspring

• transgenic organisms

Which of the following is most likely to bring together two recessive alleles for a genetic defect?

• inbreeding

• hybridization

• genetic engineering

• transformation

The crossing of buffalo and cattle to produce beefalo is an example of

• inbreeding

• hybridization

• genetic engineering

• transformation

Scientists produced oil-eating bacteria by

• making bacteria polyploid

• inbreeding bacteria

• inducing mutations in bacteria

• hybridizing bacteria

What is the ultimate source of genetic variability?

• inbreeding

• radiation

• hybridization

• mutations

Breeders induce mutations in organisms to

• increase diversity in populations

• make organisms more alike

• avoid selective breeding

• produce organisms with undesirable characteristics.

One function of gel electrophoresis is

• separate DNA fragments

• cut DNA

• recombine DNA

• extract DNA

The process of making changes in the DNA code of living organisms is called

• selective breeding

• genetic engineering

• inbreeding

• hybridization

Genetic engineering involves

• reading a DNA sequence

• editing a DNA sequence

• reinserting DNA into living organisms

• all of the above
