Cohesin-mediated cohesion between sister chromatids is established by a two-step process:

1.Loading and unloading of cohesins

2. Stabilization of cohesins

Incomplete lineage sorting (hemiplasy)

If you make a phylogenetic tree of how the alleles are related to each other, it does not mirror how the species split apart.

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 Hardy-Weinberg law, when the assumptions are met, reproduction alone does not alter allelic or genotypic  frequencies.

Hardy-Weinberg law apply to a single locus (di-allelic/ multiple allele).
