- Narrow-sense heritability is a simplification that considers only:
- In humans, hemophilia is an X-linked recessive trait. If a man and a woman have a son who has hemophilia, which of the following is definitely true?

- You are selectively breeding onions to produce the largest bulbs possible. However, after 30 generations, you observe no further increase in size generation to generation. This could be because:-All of the alleles that control size have become fixed in the population-Further increase in size is not compatible with survival of the plants
- A 66 year old man presents to your cardiology office complaining of dyspnea, angina, and exertional syncope. He reports he is otherwise healthy. On exam, you head a crescendo-decrescendo systolic ejection murmur at the right upper sternal border. Echo shows mean valve gradient of 60 mmHg. What is the best course of treatment for this patient?a. Surgical AVR with bioprosthetic valve.b. Surgical AVR with mechanical valve.c. Start the patient on a beta blocker and Aspirin.d. Percutaneous BAV.

- The patient is a 60-year-old male presenting with dyspnea and cough but denies chest pain. PE findings include tachycardia, tachypnea, friction rub, narrowed pulse pressure, and Beck's triad.

- For an inbred population, we would expect that:
- An overweight 45-year-old man comes to the emergency department because of acute chest pain that began 30 minutes ago. His pulse is 150/min with decreased peripheral pulses, and his blood pressure is 100/60 mm Hg. He was sitting at home eating dinner when he "felt his blood pressure go up," and then almost immediately experienced a sudden onset of severe, "ripping" chest pain that radiated to his back. Current medications include captopril and metoprolol, which he has not taken for several weeks. What of the following is the most appropriate imaging modality in the patient's workup?a. MRIb. Chest X-rayc. CT angiogram d. Echo
- In cucumbers, warty (W) is dominant over dull (w), and green (G) is dominant over orange (g). A cucumber plant that is homozygous for warty and green is crossed with one that is homozygous for dull and orange. The F1 generation is then crossed. If a total of 144 offspring is produced in the F2 generation, which of the following is closest to the number of dull green cucumbers expected?
