The Junco exam explores inherited and environmental influences on behaviors in juncos through various experimental setups.

Questions: 40 | Attempts: 662 | Last updated: Feb 15, 2025

Sample Question 1
The common garden experiment allowed scientists to decide whether exploratory behavior of Juncos could be inherited because

It included a genetic test of the birds’ DNA

It put city and mountain juncos in the same “neutral” place to see if their behaviors changed or stayed the same

It bred city and mountain juncos together to see whether they could produce offspring

It compared the patterns of inheritance for alleles

Sample Question 2
In the common garden experiment, the juncos from the city showed more exploratory behavior on average as compared to birds from the mountains. Which conclusion is supported about boldness behavior in juncos?

It’s learned, because the males had more exploratory behavior than females.

It’s inherited, because the males had more exploratory behavior than females.

It’s learned, because some of the mountain females’ levels of exploratory behavior were higher than the city females’ levels of behavior.

It’s inherited, because there were significant differences between city and mountain juncos in average exploratory behavior, both for males and for females.

Sample Question 3
If we wanted to compare the VARIATION in wing size between mountain juncos and city juncos, the best statistic to compare for each population would be:

The number of juncos in each population

The range of wing sizes in each population

The median wing size in each population

The mean wing size in each population
