• Investigation into family history revealed the girl's paternal great-great-grandfather was of Russian (Slavic) descent, who married a Chinese woman in the 20th century.
• Recessive genes for blonde hair and blue eyes remained hidden for three generations as only boys were born, and these traits did not activate in them.
• The recessive genes suddenly manifested in the daughter, leading to the family's surprise and the story going viral.
