Biparental inheritance chloroplast
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 … 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 …
