Assumptions—If a population is large, randomly mating, and not affected by  mutation, migration, or natural selection.

Prediction 1 —The allelic frequencies of a population do not change

Prediction 2- The genotypic frequencies stabilize after one  generation in the proportions p2, 2pq, and q2.

The short (∼20 amino acid) C-terminal tails of both α- and β-tubulin that protrude from the microtubule are enriched in glutamic and aspartic acids, the surface of the microtubule possesses a net negative charge.
