deleted constructor inheritance

One of the requirements of constructor inheritance is that the derived class can not have any constructors with the same signature. I am unsure however about how deleted functions behave under these rules.

class Foo
{
    Foo() = delete;
    Foo(const Foo& a_Foo) = delete;
};

class Bar : public Foo
{
    using Foo::Foo;
    Bar();
    Bar(const Bar& a_Bar);
};

• Are deleted constructors inherited at all?
• If so, Bar() and Foo() have the same signature, does this make the code invalid?
• You could argue that Foo(const Foo& a_Foo) and Bar(const Bar& a_Bar) have different signatures. How do copy constructors behave under constructor inheritance?
