XmlSerialzer error when multiple nillable elements of userdefined

Hi i am getting the following error while using XMLSerializer
XmlSerializer ser = new XmlSerializer(t ypeof(Person));

ERROR:
Unable to generate a temporary class (result=1).
error CS0266: Cannot implicitly convert type 'XSD.BiodataGen der?' to
'XSD.BiodataRac e?'. An explicit conversion exists (are you missing a cast?)

I am getting the above error when my xsd has multiple nillable elements of
userdefined type. If I change the type of either race or gender to String i
am getting any error. temporary class is generated easily

MY XSD :
<?xml version="1.0" encoding="UTF-8" ?>
<xsd:schema targetNamespace ="http://my/ex" xmlns:version1= "http://my/ex"
