Arrhenotoky
Encyclopedia : A : AR : ARR : Arrhenotoky
Arrhenotoky or arhenotokous parthenogenesis is a form of parthenogenesis in which unfertilised eggs develop into haploid males.
This form is observed in some marine invertebrates, scorpions, mites, bees, etc.
For some invertebrates it is a form of sex determination: males are produced pathenogenetically, while diploid females are produced biparentally from fertilized eggs.
