Best Answer: Curly hair is dominant and straight hair is recessive. Wavy hair IS a result of incomplete dominance. You could have super curly hair even if both your parents have wavy hair. Wavy hair is actually incomplete dominant. If you do the Punnett Square method it will show that to be true. Curly hair is dominant and straight is homozygous recessive. Thus producing a wavy haired child. Two parent with wavy hair should produce a wavy haired child because of the phenotype wavy was produced.
In fact, in the old days it was. Back then there was a gene that came in two versions, straight and curly. People with straight hair had two copies of the straight version, people with curly hair had two curly versions and people with wavy hair had one of each. So your case would be pretty easy to explain. You and your husband have one straight and one curly version of the gene which explains your wavy hair. Your curly haired son got a curly version from you and your husband and your other kids got only straight versions from each of you. Simple and neat. Since then things have become a bit more complicated.
