is the emergence of males before females, and it was observed for C.
In many moths and butterflies, as well as in other insects, males mature sexually before females, which is a type of protandry

Sexual development in fish is characterized by many factors, including genetic and environmental, male and female heterogametes, single gene and polygenic systems, protandry
, protogyny, social influence on sexual determination and many combinations and variations between and with these systems.
Despite this diversity, Robbrecht (1988) pointed out the presence of three reproductive strategies common in Rubiaceae-distyly, morphologically characterized by the presence of two inter-compatible floral morphs, which is generally observed in species of Rubioideae (Barrett, 1992); stylar pollen presentation involving protandry
and pollen presentation in the style which is generally recorded in Ixoroideae (De Block and Igerscheim, 2001; Nilsson et al.
Protogyny and protandry
are the underlying mechanisms favouring allogamy in monoecious palms.
