Reciprocal Aborigine-White crosses produce similar genetic results. Nasal root depression in Aborigines involves 2-3 cumulative genes sometimes overridden by dominant European high narrow nose. Aboriginal brow ridges prominent in males but less in females with inheritance unknown. Wide Aboriginal nostrils depend on few additive genes versus narrow White nose. Aboriginal thick lips feature single-gene eversion of lower lip distinct from Negro everted lips and present in Europeans. F1 Aborigine-White hybrids have skin near white. F1 backcrossed to White yields mostly white-skinned children none darker than parents. Aborigines carry single main skin melanin gene plus minor gene producing brunet-white skin. Aboriginal skin reddish-brown or chocolate with far less melanin than Negro black skin and highly tannable. Aborigine skin color genetics differs completely from African races. Hybrids show Caucasian-like skin and facial features confirming anthropological views. Aboriginal skulls dolichocephalic with 20% smaller cranial capacity than European. Archaic heavy brow ridges and nasal notch most persistent in Aborigine hybrids. Aboriginal skull resembles Mount Carmel Neanderthaloids more than other archaic forms. Aborigines especially SE groups hairy like Ainu and Indian jungle tribes. Miscegenation harmless as half-castes with Whites produce white or near-white skinned near-European featured children.
