Much less is known about the inheritance of plant mtDNA, but it seems to be commonly maternally inherited.
WebDec 5, 1995 · In nearly all eukaryotes, at least some individuals inherit mitochondrial and chloroplast genes from only one parent. There is no single mechanism of uniparental … Biparental inheritance is a type of biological inheritance where the progeny inherits a maternal and a paternal allele for one gene. It is one of the criteria for Mendelian inheritance. Sexual reproduction, where offspring result from the fusion of gametes from two parents, is the most common form of biparental inheritance. While less common, cases of biparental inheritance in extranuclear genes have been documented, such as biparental inheritance of mitochondrial DNA, or chloroplast DNA in …
WebJan 1, 2007 · The inheritance of chloroplast DNA has historically been thought to be exclusively from the maternal parent in angiosperms ( Corriveau and Coleman, 1988; Birky, 1995 ). However, studies in recent … WebThe number of recombination events in the genealogy of the chloroplast suggests that recombination, and thus biparental inheritance, is not rare. Consistent with the evidence of recombination, we find that the ratio of the number of nonsynonymous to the synonymous polymorphisms per site is lower in chloroplast than in the mitochondria genome.
