biparental inheritance

biparental inheritance

(1) Normal mendelian inheritance, in which the progeny inherits a maternal and a paternal allele of a gene.
(2) A type of extranuclear inheritance, in which both parents contribute organellar DNA to the progeny, as occurs in biparental mitochondrial inheritance in Saccharomyces cerevisiae (a yeast).

If biparental inheritance is established, IC analysis can be performed.
This low rate of incidence may have been unperceived by the Talmud Sages, or it may have been recognized as an anomaly, causing the Sages to disregard biparental inheritance of genetic coagulation disorders as a significant halakhic factor.
In the vegetative cell of pollen grain, plastid DNA breaks down from pollen mitosis independently of maternal or biparental inheritance (Sodmergen et al., 1992).
Biparental inheritance is very rare in angiosperms and has been described in only a few species--namely, Medicago sativa (Schumann & Hancock, 1989; Corriveau et al., 1990), Daucus (Hause, 1991), Pelargonium zonale (Sodmergen et al., 1992, 1994, 1998), Rhododendron mucronatum (Nagata et al., 1999a), and Pharbitis nil (Nagata et al., 1999b)--without any report on the mechanism of plastid distribution during pollen development.
In species with biparental inheritance, however, plastid DNA is intensively synthesized during the end of pollen maturation (Miyamura et al., 1987), and DNA content is multiplied up to twelvefold (Nagata et al., 1999b).
Nonetheless, there is now substantial evidence that many plant species exhibit biparental inheritance of plastid or mitochondrial genomes (Metzlaff et al.
