A newly described rare and potentially fatal condition causes heart rate to be unusually low in adults (between 30-45 beats per minute). A series of studies have shown a possible genetic link. Normal heart rate in adults is typically between 60 to 100 bpm. A family's medical chart that includes afflicted individuals is provided below. As a medical researcher, your supervisor asks you to produce a pedigree of this family to visualize and to determine a possible pattern of inheritance for this condition. As such, based on the data, draw the pedigree (clearly identifying who is afflicted and not afflicted) and your conclusion as to the mode of inheritance of this condition. Explain your reasoning.
