Answer:
The creation of the limbs is carried out by AER and ZVP. AER stands for apical ectodermal ridge and ZVP stands for polarising activity line.
Explanation:
- AER is responsible for the developmental progression in the distal to the anterior region and the ZVP is liable for the progressive advancement in the posterior to a backward region.
- AER and ZVP are interconnected on one another in the secretion of a sonic hedgehog, which eventually assists throughout the hox speech to promote the growth of the arm.
- The hypothesis that the new short-arm gene inhibits the effect of FGF (fibroblast growth factors) on AER can be tested and use a template of cultured cells.
- The AER may be disrupted in the model and the impact of the gene encoding on FGFs may be examined. If in the existence of a viral vector, the role of the FGFs is to trigger correct growth, then the hypothesis is incorrect, or else the hypothesis is right. The FGF8 is by far the most powerful of all as the result.

Answer:
Explanation:
Insertion/deletion of 3 base which is a condon will be less fathal because only one amino acid will be missing from the protein of which the gene codes for.
If one codon is deleted it will still be the same but might cause a disease for example in cystic fibrosis one amino acid, 508th Phenly alanine is missing in the CFTR protein. They severity of diseases caused by Insertion or deletion is increased as the number of condon are more.
However, if only one or two is deleted/inserted then all the codons will shift causing them to be in different groups which may form a totally different amino acids as seen in frameshift mutation. This is more dangerous.
