Question 3: we have discussed the cell biology of the genetic disease cystic fibrosis (cf). the most common
cftr variant associated with cf is a deletion of a phenylalanine at position 508 in the protein sequence. this
is due to the deletion of a codon in the dna sequence that codes for cftr protein.
a. two healthy parents have a healthy son and a daughter with cf. what is the inheritance pattern for cf?

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
