Question

artificial selection - textbook summary
directions: use the document linked above to fill in the blanks below
how can traits be directly influenced?

1. the selection and breeding of organisms with desired traits is
2. darwin saw that changes caused by selective breeding were much like changes caused by
3. the organisms that result can have a that are different from those of the original organisms.

what is genetic engineering?

1. recall that chromosomes are made of
2. is the biological and chemical methods that change the arrangement of dna that makes up a gene.
3. to make dna, scientists insert a useful segment of dna from one organism into a bacterium.
4. therapy is the replacement of missing or malfunctioning genes by the addition of new genes to a patients cells.

what is a genetically modified organism?

1. food products that have been genetically modified are commonly referred to as organisms, or gmos.
2. genetic engineering can produce plants that are bigger or that grow faster. might produce more fruit, seeds, or offspring.

dna selective breeding phenotype and genotype natural selection gene genetic engineering gmos genetically modified recombinant

Explanation:

1. The selection and breeding of organisms with desired traits is called selective breeding.
2. Darwin saw selective - breeding changes as similar to natural selection changes.
3. Resulting organisms can have a phenotype and genotype different from the original ones.
4. Chromosomes are made of DNA.
5. Genetic engineering changes the DNA arrangement of a gene.
6. Inserting DNA segments into bacteria creates recombinant DNA.
7. Gene therapy replaces malfunctioning genes.
8. Genetically modified food products are called GMOs.
9. Genetically modified plants may produce more fruit etc.

Answer:

1. selective breeding
2. natural selection
3. phenotype and genotype
4. DNA
5. Genetic engineering
6. recombinant
7. Gene
8. genetically modified
9. genetically modified
