SUMMARYLaying workers of Apis mellifera capensis E SCHOLTZ producing impatemate offspring are normal diploids with 2n = 32 chromosomes. During the first maturation division, chromosome pairing, synapsis, chiasmata and diakinesis were observed. Thus a reduction division occurs resulting in a haploid set of 16 chromosomes.During anaphase II four nuclei are formed, arranged in a line parallel to the egg surface. Later two central nuclei, i.e. the egg pronucleus and the central descendant of the first polar body (second division non-sister nuclei) fuse to form the (diploid) zygote nucleus.
