Answer:
Option (c).
Explanation:
The hemoglobin is the important protein present in the red blood cells. The hemoglobin molecules helps in the transport of oxygen and carbon dioxide in the body. 
The iron is important for the hemoglobin molecule formation. The deficiency in the iron can cause the abnormal hemoglobin structure. The mice hemoglobin can binds with the only 50% of the oxygen molecules as compared with the wild type mice.
Thus, the correct answer is option (c).
 
        
             
        
        
        
Answer:
it is expected that the mutation results in a reduced initiation of translation and thereby decreasing the level of the protein A, while it does not change the level of mRNA A
Explanation:
Translation in bacteria starts with the formation of the initiation complex which is composed of the small ribosomal subunit, the messenger RNA (mRNA), initiation factors and the initiator transference RNA (tRNA) containing N-formyl-methionine. The small ribosomal subunit binds to a polypurine stretch of variable length in the mRNA called 'the Shine-Dalgarno sequence'. A mutation in this sequence reduces the affinity of the ribosome for the mRNA, thereby, in this case, decreasing the level of protein A. Since transcription occurs before translation, it is expected that this mutation does not change the level of expression of the mRNA A.
 
        
             
        
        
        
What alleles do the parents have? If the parents are both Homozygous recessive the answer is 0%. If one is homozygous dominant it doesn't matter what the other one is, the answer is 100%. if the are both heterozygous the answer is 75%
