Congenital deafness in humans is due to the homozygous condition of either of the recessive genes d
or e, or both of these genes. Both dominant D and E are necessary for normal hearing. Gene D/d affects the middle ear, while gene E/e affects the inner ear. It does not matter how good the normal inner ear (as indicated by E__) is; if there is something wrong in the middle ear, the individual is unable to hear. The same applies for the other gene. Give the phenotypic results of the following crosses: (a) Dd EE ? Dd EE (b) Dd Ee ? Dd Ee (c) dd EE ? DD ee (d) Dd EE ? Dd ee (e) Dd EE ? DD Ee What will be an ideal response?
