Answer:
1)A genotype is an organism's complete set of genetic material. Often though, genotype is used to refer to a single gene or set of genes, such as the genotype for eye color. The genes take part in determining the characteristics that are observable in an organism, such as hair color, height, etc.
2)An inherited life-threatening disorder that damages the lungs and digestive system.
Cystic fibrosis affects the cells that produce mucus, sweat and digestive juices. It causes these fluids to become thick and sticky. They then plug up tubes, ducts and passageways.
3)Individual III-5 is male. Individual III-5 is affected by the genetic condition. Individual III-5 is the proband.
