Perform this investigation. Create a dichotomous key based on the characteristics of various fruits
1. Choose a group of five or more different fruits. It may be helpful to keep a picture of your group of fruits or the fruits
themselves together so that it is easier to make your key and identify the fruits that you are using
2. If you do not have the fruit on hand, look up a picture online or from any other suitable reference material.
3. Carefully examine or think about the characteristics of the fruits and create a dichotomous key using some of these
characteristics. The list provided in the experiment should give you an idea of some of the fruits and/or characteristics
that could be used, but you are free to use any of your own choosing
apples (red)
oranges
bananas
cherries
lemons
pears
tomatoes
watermelons (oblong)
cantaloupes
plums (red)

To answer this question, researchers studied populations of the dusky salamander (desmognathus ochrophaeus) living on different mountain ranges in the southern appalachian mountains. the researchers tested the reproductive isolation of pairs of salamander populations by leaving one male and one female together and later checking the females for the presence of sperm. four mating combinations were tested for each pair of populations (a and b)—two within the same population (female a with male a and female b with male b) and two between populations (female a with male b and female b with male a). the proportion of successful matings for each mating combination was measured. for example, when all the matings of a particular combination were successful, the researchers gave it a value of 1; when none of the matings were successful, they gave it a value of 0. then the researchers calculated an index of reproductive isolation that ranged from 0 (no isolation) to 2 (full isolation). the reproductive isolation value for two populations is the sum of the proportion of successful matings of each type within populations (aa + bb) minus the sum of the proportion of successful matings of each type between populations (ab + ba). the table provides data for the geographic distances and reproductive isolation values for 27 pairs of dusky salamander populations.
