<h2>Collagen genes is the best choice</h2>
Explanation:
Collagen is the most abundant protein in mammals
- Collagen is found in bones,muscles,tendons and skin
- It is the one which holds the body together
- It strengthen and support many tissues in the body
- Collagen genes encode many types of collagen which have a structural role in the extracellular matrix and has a great tensile strength
- At least 26 different collagen polypeptide chains are present which are encoded by 26 unique collagen genes
- Since collagen is the main protein of connective tissue in animals and is considered as the most abundant protein in mammals it can be the best choice to base the phylogeny
- Rest all options are specific for a particular function in particular animals
