The fruit rots less fast
If you think about the mechanisms of artificial selection and Darwinian selection, traits
need to be heritable and there needs to exist variation for selection to act on.
Thus, the correct answer is:
It needs to be possible that a trait can be passed from parent plant to offspring
Correct! Highest amount of work per
Not all individuals within a population are the same for a particular trait D
harvested plant calorie
Correct! Fully wild-type plant material is A
harvested with no replacement
planting
Question 4 pts
Correct! Land is cleared and tilled, and the C
If a domesticated plant were to be released into the habitat where its closest wild relative does plant material is not quite wild-type
best, how would this plant do in comparison to its wild ancestor? yet but also not quite fully
domesticated yet.
Better
Correct! Lowest human population density A
Correct!
Worse
Correct! Land is NOT cleared but humans
Equally well B
might plant seeds to replace what
they have harvested.
It is impossible to come up with a hypothesis with this scenario
good
Question 6 pts
From the perspective of the farmer, seed dispersal is favorable
Question 5 pts
True
Correct!
As we learned in class, there are four generally accepted stages (A to D) from how humans False
gather wild plants to how they grow domesticated plants. Match the following terms to these
four stages.
Question 7 pts
With a high seed dispersal ability, the next generation of plants is more likely to inbreed
True
