Bind does the forward resolution of example.com. daughter1.example.com.
and daughter2.example.com. to your ip.

Apache does the virtual hosting from your ip using one incarnation
for example.com. using a different one for daughter1.example.com. and
a third one for daughter2.example.com.

The reverse resolution from your ip will resolve only for example.com.

Using /etc/hosts you could have

192.0.12.66   example.com  daughter1.example.com  daughter2.example.com.

Then gethostbyname would return example.com and the aliases
daughter1.example.com  daughter2.example.com.

Sorry bind was never designed that intelligent. That piece of
information got lost with DNS.
