Is stammering Criss cross pattern of inheritance?
Hello aspirant,
Criss-cross inheritance is inheritance of X linked characters. The characters are transferred from mother to her son and from father to his daughter. Hemophilia C is an example.
Stammering although is a genetic disorder but there is no research yet to classify it under disorder of X linked inheritance. The exact pathophysiology of developmental stammering is unknown. Genetic and environmental factors play a vital role in the onset of stammering. Various family and twin studies indicate that the genetic influence is not in the form of an exact single gene effect such as autosomal recessive, autosomal dominant, or x-linked in all families. However, some studies have repeatedly implicated heredity as a major factor in the occurrence of stammering .
So, stammering is not criss-cross pattern of inheritance.
Hope this helped.
