discovered the phenomenon of parthenogenesis in bees; designed the first successful movable-frame beehive Johann Dzierzon , or Jan Dzierżon [ˈjan ˈd͡ʑɛrʐɔn] or Dzierżoń [ˈd͡ʑɛrʐɔɲ] , also John Dzierzon (16 January 1811 – 26 October 1906), was a Polish apiarist who discovered the phenomenon of parthenogenesis in bees .
Parthenogenesis occurs naturally in some plants, algae, invertebrate animal species (including nematodes, some tardigrades, water fleas, some scorpions, aphids, some mites, some bees, some Phasmatodea, and parasitic wasps), and a few vertebrates, such as some fish, amphibians, and reptiles. This type of reproduction has been induced ...
Honey bees produce haploid males from unfertilized eggs. Arrhenotoky (from Greek ἄρρην árrhēn "male" and τόκος tókos "birth"), also known as arrhenotokous parthenogenesis, is a form of parthenogenesis in which unfertilized eggs develop into males. In most cases, parthenogenesis produces exclusively female offspring, hence the ...
Parthenogenesis is a form of agamogenesis in which an unfertilized egg develops into a new individual. It has been documented in over 2,000 species. [20] Parthenogenesis occurs in the wild in many invertebrates (e.g. water fleas, rotifers, aphids, stick insects, some ants, bees and parasitic wasps) and vertebrates (mostly reptiles, amphibians ...
Parthenogenesis is a natural form of reproduction in which growth and development of embryos occur without fertilisation. Thelytoky is a particular form of parthenogenesis in which the development of a female individual occurs from an unfertilized egg. Automixis is a form of thelytoky, but there are different kinds of automixis. The kind of ...
Aphid giving birth by parthenogenesis, the live young growing from unfertilized eggs. Thelytoky (from the Greek θῆλυς thēlys "female" and τόκος tókos "birth") is a type of parthenogenesis and is the absence of mating and subsequent production of all female diploid offspring as for example in aphids.
Parthenocarpy is sometimes claimed to be the equivalent of parthenogenesis in animals. [13] That is incorrect because parthenogenesis is a method of asexual reproduction, with embryo formation without fertilization, and parthenocarpy involves fruit formation, without seed formation. The plant equivalent of parthenogenesis is apomixis.
The male bees' genetic makeup is therefore entirely derived from the mother, while the genetic makeup of the female worker bees is half derived from the mother, and half from the father. [12] Thus, if a queen bee mates with only one drone, any two of her daughters will share, on average, 3 ⁄ 4 of their genes.
