GynodioecyGynodioecy is a rare breeding system that is found in certain flowering plant species in which female and hermaphroditic plants coexist within a population. Gynodioecy is the evolutionary intermediate between hermaphroditism (exhibiting both female and male parts) and dioecy (having two distinct morphs: male and female). Gynodioecy is sometimes considered a mixed mating system comparable with trioecy and androdioecy.
DioecyDioecy (from Ancient Greek (dioikía)'two households'; adj. dioecious) is a characteristic of species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only the females directly produce offspring.
CaryophyllaceaeCaryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants. It is included in the eudicot order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactaceae, and Polygonaceae. It is a large family, with 105 genera and about 2,625 known species. This cosmopolitan family of mostly herbaceous plants is best represented in temperate climates, with a few species growing on tropical mountains.
Carl CorrensCarl Erich Correns (19 September 1864 – 14 February 1933) was a German botanist and geneticist notable primarily for his independent discovery of the principles of , which he achieved simultaneously but independently of the botanist Hugo de Vries, and for his acknowledgment of Gregor Mendel's earlier paper on that subject.
Flowering plantClade of seed plants that produce flowersFlowering plants are plants that bear flowers and fruits, and form the cladeAngiospermae (). The term angiosperm is derived from the Greek words ἀγγεῖον (angeion; 'container, vessel') and σπέρμα (sperma; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta.
Gregor MendelGregor Johann Mendel (; German: [ˈmɛndl̩]; Czech: Řehoř Jan Mendel; 20 July 1822 – 6 January 1884) was an Austrian biologist, meteorologist, mathematician, Augustinian friar and abbot of St. Thomas' Abbey in Brno (Brünn), Margraviate of Moravia. Mendel was born in a German-speaking family in the Silesian part of the Austrian Empire (today's Czech Republic) and gained posthumous recognition as the founder of the modern science of genetics.
Charles DarwinCharles Robert Darwin ( DAR-win; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental scientific concept.Herbert G. BakerHerbert George Baker (February 23, 1920 – July 2, 2001) was a British-American botanist and evolutionary ecologist who was an authority on pollination biology and breeding systems of angiosperms. He described what became known as "Baker's rule," a theoretical proposal underpinning an empirical observation that the ability to self-fertilize improves colonization ability among plants by increasing the probability of successful establishment after long-distance dispersal.
Janis AntonovicsJanis AntonovicsFRS (Latvian: Jānis Antonovics; born 1942 in Riga, Reichskommissariat Ostland) is an Americanbiologist, and Lewis and Clark Professor of Biology, at University of Virginia. LifeHe was educated at Gravesend Grammar School (1953–1960), graduating from Clare College, Cambridge with a B.A. in 1963, and from University of Wales with a Ph.D. in 1966. He lectured at Institute for Advanced Study, Berlin. HonorsHe is a 1991 Guggenheim Fellow.
Family (taxonomy)Family (Latin: familia, pl.: familiae) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus.
GenusGenus (; pl.: genera) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. E.g. Panthera leo (lion) and Panthera onca (jaguar) are two species within the genus Panthera.
GynomonoecyGynomonoecy is defined as the presence of both female and hermaphrodite flowers on the same individual of a plant species. It is prevalent in Asteraceae but is poorly understood. It is a monomorphic sexual system comparable with monoecy, andromonoecy and trimonoecy. OccurrenceThis sexual system occurs in about 2.8% of flowering plants. It is present in 3% of Silene species and 23 families of flowering plants, but is most common in the daisy family, Asteraceae.*As an Amazon Associate I earn from qualifying purchases.
