A “Jaglion” is the offspring between a male Jaguar and a female Lion. Jaglions have only been born in zoos and animal sanctuaries. Jaglions are able to live to adulthood. It is unknown whether Jaglions are able to produce viable, fertile offspring. If researchers find that Jaglions produce offspring that cannot reproduce, would you conclude that Jaguars and Lions are the same species or different species? Remember the definition of species that we discussed in class and in the pre-class video.

On average, out of 1000 DNA base pairs, how many are the same for two randomly chosen humans?

What do we mean when we say that populations of chimpanzees have five times as much variation as populations of humans?

If you were to find that all humans from Africa had allele 1, all humans from Europe had allele 2, and all humans from East Asia had allele 3 at a locus you are studying, what might you hypothesize about gene flow in human populations over the past 200,000 years (since humans started migrating out of Africa)?

  The two sets of pie charts above show two possible results from a study like the Rosenberg study that we examined in class. Both possibilities show possible results for the same locus. Colors show different alleles. For each statement, select whether possibility 1, possibility 2, neither possibility, or both possibilities support the statement. Options may be used more than once.   Prediction 1) There is more variation within geographic regions than between geographic regions. [blank1]   Prediction 2) There is more variation between geographic regions than within geographic regions. [blank2]   Prediction 3) It is possible to identify someone’s geographic origin based on their allele at this locus. [blank3]   Prediction 4) It is impossible to identify someone’s geographic origin based on their allele at this locus. [blank4]

If a group of rabbits had a high mutation rate and frequently had new rabbits migrate into their group, what would happen to the amount of genetic variation in this rabbit population over time?

On the first day of class, we looked at data and watched a video about male superb birds-of-paradise and their mating displays. Examine the figure and legend and indicate whether each statement is true or false: 1) Male birds vary in their display quality [1a] 2) Male birds likely differ in their reproductive success [2a] 3) The figure tells us that male display quality will increase over the coming generations [3] 4) The dependent variable is male display quality rank [4b] 5) The sample size for low display quality males is seven [5] 

While sitting outside looking at a tree, you notice that all of the caterpillars are on the bottom of the leaves and not on the top. This is most closely associated with which step in the scientific method?

Achromatopsia, a form of colorblindness, affects an estimated 1 in 30,000 people worldwide.  Pingelap is an island and part of the Federated States of Micronesia. In the late 18th century a typhoon hit and the human population on the island went from 500 people to about 20 people. The survivors reproduced and by the 1900s the population was back to about 600 people. However, the incidence for achromatopsia in the Pingelap population is now about 1 in 1,800 people. Which process of evolution has most likely occurred?

A scientist wants to study bird predation of peppered moths. In a natural environment, they put light moths and dark moths on the trunks of trees and observe the moths for 30 minutes. The scientist records if each moth was eaten. What was a controlled variable in this experiment?
