Answer: a

3. Which is an accurate statement regarding transgenic organisms and wild populations?

a. It is improbable that transgenic organisms could disrupt wild populations.

b. Native species have greater genetic diversity than transgenic organisms.

c. The impact of transgenic organisms on ecologic balance is unknown.

d. Transgenic organisms will likely dominate and replace native species.

Answer: c
How is biodiversity measured in a population?
a)by careful visual analysis of native species
b)by comparing DNA fingerprints
c)by enzyme-linked immunosorbant assays
d)by population counts in the field


Answer: b
Why is biodiversity important?
a)Biodiversity is the cornerstone for creating transgenic organisms in agriculture.
b)Biodiversity is what allows species to inhabit multiple biomes throughout the world.
c)Each genetic trait may be a tremendous asset for the continuation of a species.
d)It is essential for the survival of offspring that genes of parents are recombined.


Answer: c
Why does the Agricultural Research Service seek to preserve the rare breeds that may not possess traits contributing to high production levels?
a)It is morally wrong to let an organism go extinct even if it is not productive.
b)Rare breeds are appreciated in the organic farming community and market.
c)The breeds are especially useful as surrogate mothers in the cloning process.
d)The breeds may possess valuable genetic traits, such as disease resistance.


Answer: d
How has biotechnology been applied in the management of wild populations?
a)Bacillus thuringiensis (Bt) has been inserted into wild plants to create plants that produce the Bt toxins.
b)Biotechnology can be used to detect inbreeding and the need to increase the genetic diversity of a group.
c)Biotechnology can be used to expand quality habitat thereby expanding the range of a species.
d)Threatened or endangered species can be saved by inserting genes of unrelated species.


Answer: b

What is a legitimate concern regarding genetically modified salmon?
