Nuclear Vs Cytoplasmic
Nuclear versus cytoplasmic inheritance describes where genetic material controlling a trait is located—in the cell nucleus (nuclear DNA) or in organelles like mitochondria and chloroplasts (cytoplasmic DNA). In cannabis breeding, most observable traits follow nuclear inheritance patterns, inherited predictably through Mendelian genetics from both parents. However, some characteristics, particularly those affecting chloroplast function or energy metabolism, may exhibit cytoplasmic or maternal inheritance, where traits appear to pass exclusively through the female parent. Understanding this distinction helps breeders predict trait expression across generations and troubleshoot unexpected segregation patterns in crosses.

Breeders distinguish between nuclear and cytoplasmic inheritance when analyzing stability and heritability of traits. If a desired characteristic appears only in offspring from a specific female parent regardless of pollen source, cytoplasmic inheritance may be involved, requiring different selection strategies than nuclear traits.
