Genetics race question?

i was wondering about genetics. so i started to research and i found out that when 2 genetically distant humans have children they tend to have taller more attractive and healthier physically and mentally. i happened to be half Russian and half Lebanese and i did end up 6'2 even though my parents where not as tall about 5'8 my father and 5'6 my mother and i also ended up handsome. so my question was what race would be more genetically distant to Russian and Lebanese people?
