WebJul 9, 2024 · The inheritance of chloroplast genome DNA (cpDNA) differs from that of the nuclear genome. The cpDNAs of most species originate from the female parent, whereas some plastids are paternal or biparental in origin. The plastid transmission of Pinaceae species is thought to occur exclusively by paternal inheritance with a few exceptions. … WebExtranuclear inheritance, including mitochondrial and chloroplast inheritance, occurs in eukaryotes when genetic information is transmitted by means other than through nuclear DNA.
