Income tax deduction from salary

Hello,

My father gets an annual salary of 1200000.00. According to form 16 part b given to him by his employer showing the breakup of salary, his entire income is shown as basic salary. now my doubt is that whether he can claim deductions such as house rent allowance, travelling allowance, servant allowance etc even though it is not shown separetly in his form 16, but he has got bills for all such expenses. 

Thank You in advance
