Solution
In higher eukaryotes, traits coded for in extranuclear DNA are inherited solely from the female parent.
Explanation:
In higher eukaryotes, traits coded for in extranuclear DNA are inherited solely from the female parent. This is because extranuclear DNA, such as mitochondrial DNA, is typically transmitted through the egg cytoplasm and not through the sperm, leading to maternal inheritance of these traits. Thus, extranuclear inheritance is uniparental and maternal in origin in higher eukaryotes.
