Congenital deafness in humans is due to the homozygous condition of either or both of the recessive genes d or e. 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
