Cattleya alaorii Cattleya alaorii, commonly known as the Laelia alaorii, is a species of orchid endemic to Brazil (Bahia). The species was named after Mr. Alaor Oliveira, former employee at the University of São Paulo at Piracicaba, who first collected this species in a field excursion in the late 1960s. It was discovered in the 1970s in an isolated mountain chain near Itabuna, Bahia state. It grows in
Flowering plant is the pairing of homologous chromosomes and homologous recombination (the exchange of genetic information) between homologous chromosomes. This process promotes the production of increased genetic diversity among progeny and the recombinational repair of damages in the DNA to be passed on to progeny. To explain the adaptive function of meiosis in flowering plants, some authors emphasize diversity and others emphasize DNA repair. Apomixis (reproduction via asexually formed seeds) is found naturally in about 2.2% of angiosperm genera. One type of apomixis, gametophytic apomixis found in a dandelion species involves formation of an unreduced embryo sac due to incomplete meiosis (apomeiosis)
