The Heritability of Facial Morphogenic Traits among the Ijaw People of Yenagoa: Dimple, Philtrum, Gap Teeth and Mentolabial Sulcus

Key Points

• To investigate the heritability of specific facial morphogenic traits in the Ijaw population.
• Population genetic analysis of the Ijaw people
• Assessment of facial traits: dimple, philtrum, gap teeth, mentolabial sulcus
• Comparative heritability study of facial features
• Dimpling trait shows significant heritability among Ijaw population.
• Other traits' heritability estimates remain unclear due to variability.
