Inheritance pattern of mid-digital hair amongst Igbo tribe of Nigeria

Abstract

The inheritance pattern of mid-digital hair among Igbo tribe was investigated. A total of 648 individuals were studied comprising 400 parents and 248 offspring (121 males and 127 females) from Igbo families. The expression of mid-digital hair trait was  observed, noted and pictures taken. After analysis of data obtained from the 200  families, it was observed that mid-digital hair was more common in males than females. The presence of mid-digital hair was found to be dominant over its absence following an Autosomal Dominant-Recessive pattern of inheritance. It was concluded that  observation of mid-digital hair trait might be suitable for genetic analysis.
