The males do not have to compete with other males, and female anemone fish are typically larger. When a female dies a juvenile (male) anemone fish moves in, and "the resident male then turns into a female and reproductive advantages of the large female–small male combination continue". [22] In other fishes sex changes are reversible.
A mating system is a way in which a group is structured in relation to sexual behaviour. The precise meaning depends upon the context. With respect to animals, the term describes which males and females mate under which circumstances.
a sexual system for plants when female, hermaphrodite, and gynomonoecious plants coexist in the same population. [25]: 360 Monoicy: one of the main sexual systems in bryophytes. [18] In monoicy male and female sex organs are present in the same gametophyte. [19] Monoecy: a sexual system in which male and female flowers are present on the same ...
Inflorescences can be acted on by sexual selection in many ways, and commonly include arrangement, number, and size. [5] For example, male inflorescence in plants often produce more flowers than females . Furthermore, pollen export and ultimately paternity, often increases with flower number, even for plants with hermaphroditic flowers.
Sexual dimorphism also occurs in hermaphroditic fish. These species are known as sequential hermaphrodites. In fish, reproductive histories often include the sex-change from female to male where there is a strong connection between growth, the sex of an individual, and the mating system within which it operates. [55]
In flowering plants, the flowers contain the sex organs. [26] Sexual reproduction in flowering plants involves the union of the male and female germ cells, sperm and egg cells respectively. Pollen is produced in stamens and is carried to the pistil or carpel, which has the ovule at its base where fertilization can take place. Within each pollen ...
Sexual mimicry is employed differently across species and it is part of their strategy for survival and reproduction. Examples of intraspecific sexual mimicry in animals include the spotted hyena, certain types of fish, passerine birds and some species of insect. Interspecific sexual mimicry can also occur in some plant species, especially orchids.
Species that can undergo these changes do so as a normal event within their reproductive cycle, usually cued by either social structure or the achievement of a certain age or size. [ 3 ] In animals, the different types of change are male to female ( protandry or protandrous hermaphroditism ), female to male ( protogyny or protogynous ...
