Dr. McCallum's class is learning about genes. He explains that not all of the information contained in our genes is used, either because the environment doesn't trigger certain tendencies, or because another genetic tendency took precedence. The genetic information that IS active in a particular person is expressed through observable characteristics. We call these characteristics

Liam's father has blue eyes, but Liam has brown eyes, like his mother. As an adult, Liam marries a woman with blue eyes, and now they are expecting their first baby. Is it possible for the child to be born with blue eyes?
|A)||Yes. Liam may carry the recessive gene for blue eyes.|
|B)||Yes. When one parent has blue eyes and the other has brown, the child always has a 50% chance of getting the blue eyes.|
|C)||No. As long as one parent has brown eyes the child will always have brown eyes.|
|D)||No. Since Liam has brown eyes, he only carries genes for brown eyes.|
Tahki and Waneta are identical twins, but they were separated at birth and raised in different countries. When they meet as adults, they talk about all the ways in which they are the same, but also the ways in which they are different. Compared to identical twins that have been raised together, Tahki and Waneta probably
|A)||have more characteristics in common than most twins because they didn't have to prove to anyone that they are different.|
|B)||are as similar as identical twins who were raised in the same household.|
|C)||have fewer characteristics in common than most twins because their environments were different while they were growing up.|
|D)||have the same percentage of similarities as non-identical siblings.|
Researchers have determined that bipolar disorder is more heritable than a major depressive disorder. They found that the more closely related family members are to someone with bipolar disorder, the more likely they are to have bipolar disorder themselves. The correlation is not as strong with major depressive disorders. These types of researchers are referred to as
A researcher has decided to lesion different parts of a cat's brain and observe the effects on the cat's behavior. After the surgery, the researcher notices that the cat is having trouble walking in a straight line. The cat also does not respond to the researcher randomly blowing a whistle like it did before the surgery. The researcher also noted that the cat's sleep/wake cycle has changed since the surgery. What part of the brain did the researcher most likely lesion?

|A)||Tim's injury was to Broca's area and John's was to Wernicke's area|
|B)||Tim's injury was to Wernicke's area and John's was to Broca's area|
|C)||Tim's injury was to the somatosensory cortex and John's to the primary motor cortex|
|D)||Tim's injury was to the left hemisphere and John's was to the right hemisphere|
