To know: The probability for two genetic crosses in the given case. Introduction: Cystic fibrosis is a disease that is caused due to defective genes. It is a recessive disorder that is passed on to children by their parents. It can affect the lungs, pancreas, and digestive system . It is caused when both parents are carrying one recessive gene and children must inherit both genes in order to get affected.

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.
