During S phase

DNA-bound G1 cohesins Convert into cohesive complexes by cohesin acetyl transferases (CoATs)

which acetylate Smc3 subunit & prevents unloading of cohesins by Pds5-Wapl, thereby stabilizing the cohesins on chromosomes.

In the Hymenoptera (ants, bees, and wasps), Females develop from the queen’s fertilized eggs and are diploid. Males develop from the queen’s unfertilized eggs and are haploid—their sperm are genetically identical
