We would normally have 6 fingers if so. Your sub question doesn't make sense as both options are the same. Title: Do humans have a dominant trait for six fingers instead of five? Post by: smither on Apr 4, 2013 Yes http://www.brighthub.com/science/genetics/articles/47390.aspx
Title: Do humans have a dominant trait for six fingers instead of five? Post by: TOPPINGS on Apr 4, 2013 Yes, actually! It's called Polydactyly and it is caused by an autosomal dominant allele. Usually the extra digit is just a little extra tissue, but every once and a while a full functioning finger (or toe) can form!
