‘Meiosis produces 4 gametes, ie. isogamy, anisogamy and oogamy, which through mitosis develops into mature gametes.’
‘Isogamy and anisogamy, and sometimes oogamy, may occur.’
‘In many species with gametes of different sizes (anisogamy), sexual crosses typically produce progeny with mitochondrial DNA inherited from the larger gamete.’
‘Orders that are characterized by oogamy (or pronounced anisogamy) and are reported to have large female gametes have the largest nuclear genomes observed regardless of their phylogenetic position.’
‘A popular theory has proposed that anisogamy originated through disruptive selection acting on an ancestral isogamous population.’
‘The principle behind anisogamy is a division of the labour necessary for two gametes to unite and successfully develop.’
‘The principle behind anisogamy is a division of the labour necessary for two gametes to unite and successfully develop.’
‘Since anisogamy (gametes of different sizes: eggs and sperm) is what defines the sexes it is thus a prerequisite for sexual dimorphism.’
Origin
Late 19th century from Greek anisos ‘unequal’ + -gamy (from gamos ‘marriage’).
