Etymology
Etymology Information

'arrhenotoky' originates from Modern New Latin/Greek technical coinage, specifically from Greek elements 'arrhen-' and '-toky' (from 'tokos'), where 'arrhen-' meant 'male' and 'tokos' meant 'birth' or 'offspring'.

Historical Evolution

'arrhenotoky' was formed in scientific usage (Modern New Latin/English) in the 19th century from Greek-derived components; it relates to the adjective 'arrhenotokous' and earlier New Latin formations before becoming established in modern biological terminology as 'arrhenotoky'.

Meaning Changes

Initially it literally meant 'male birth' from the Greek roots; over time it came to be used specifically in biology to mean 'the production of male offspring from unfertilized eggs' (a type of parthenogenesis).
