The similarity of 94% in their DNA sequence suggest that they have originated from a common ancestor and are closely related species.

Explanation:

The difference in DNA sequences in different species is due to the accumulation of genetic variation in the course of natural selection and evolution. Less is the difference in DNA sequences of two organisms the more related they are.

Genes determine the characteristics in an organism, and they are DNA sequences determining the protein to be formed. The similarity in DNA sequence of two species establish the evolutionary relationship among them.

Due to the genetic variation in species, the natural selection of the species had caused the evolution of the species adapted well to the environment.

Cystic fibrosis is a recessive genetic disorder that result from a defective gene on chromosome 7. For an individual to have sym

spin [16.1K]

Answer:

Cystic fibrosis is a genetically transmitted or heriditary disease.

Explanation:

In cystic fibrosis the lungs and the digestive system get effected. It causes the CFTR protein (Cystic Fibrosis Transmembrane conductane Regulator) to become dysfunctional. Due to this dysfunction, chloride become unable to move. for this reason mucus clogs the airways in the lungs which leads to respiratory failure and other complications. The gene responsible of this disease located at the long arm of chromosome number 7. Of all ethnic groups, caucasians have the highest inherited risk of this disease.
