Answer to Question 1

B

Answer to Question 2

Sickle-cell trait is an asymptomatic condition in which the patient received the genetic trait from only one parent. Sickle-cell anemia occurs when a patient received the genetic trait from both parents and, therefore, develops an abnormal type of hemoglobin in the red blood cell, causing decreased oxygenation in the tissues.
