Can I again declare virtual method as virtual in child class???

public class baseclass{
    public virtual void MyMethod(){
    }
}

public class subclassOne : baseclass{
    public override void MyMethod()
    {
        base.MyMethod();
    }
}

public class subclassTwo : baseclass{
    public sealed override void MyMethod()
    {
        base.MyMethod();
    }
}


public class secondlevelClass : subclassTwo{
    public override void MyMethod()
    {
        base.MyMethod();
    }
}
