Summary

This article from the 1928–1936 Soviet Great Medical Encyclopedia defines androgenic eggs as eggs that develop into males, noting morphological differences in certain worms and rotifers, parthenogenetic development in bees, and chromosomal differences in chickens and some butterflies.

Encyclopedia entry (1928–1936)

ANDROGENIC EGGS, eggs from which males develop. They may differ in their external appearance (for example, in the worm Dinophilus and in rotifers); in these forms, they are much smaller than the eggs that produce females. In bees, they develop parthenogenetically, in contrast to the eggs that produce females and workers, which develop with fertilization. In chickens and some butterflies, they differ from the eggs that produce females by their chromosomal apparatus: in chickens, androgenic eggs possess a Z-chromosome, while the eggs producing females possess a W-chromosome (see Sex).
