With pedigree dog breeders can also find out whether a dog is purebred or not purebred.

Answer:
Elongated shape
Explanation:
Centrifugation separates molecules on the basis of angular motion.
Due to spherical shape, the value of 'f' is lesser for a spherical protien than the rod shaped one.
Hence the sedimentation coefficient for an elongated protien is 2.6S while htat of a spherical protien is 4.31S.
Hence its elongated shape results in slow centrifugation.
Some of the important principles of centrifugation are as follows :
- The greater the mass, the more is the sedimentation rate i-e the one with greater mass will move down more rapidly as compared to the one with les mass.
- Shape of particles also effect it, the rounder the particle, the lower frictional coeeficient.
- Density of particles
- Density of fluid
