The creation of fees simple conditional as they existed under the law of England prior to the statute de donis is not permitted. The creation of fees tail is not permitted. The use in an otherwise effective conveyance of property, of language appropriate to create such a fee simple conditional or a fee tail, creates a fee simple in the person who would have taken a fee simple conditional or a fee tail. Any future interest limited upon such an interest is a limitation upon the fee simple and its validity is determined accordingly. Nothing herein contained shall affect the operation of sections 76-111 to 76-113.
