This in reply to your 5/31 post What about their mother? (fivedoves.com) in which you asked the following questions about the mother of the sons of the giant Ishbibenob:

"But was their mother also a giant, a female giant, or was she a regular sized woman?

Were there female giants amongst the Anakims, Emims, Horims, Avims, Zamzummims, Rephaims, or the Zuzims?

Or were all the giants male?

Those were after the flood.

But what about the giants before the flood, were any of them female?"

First of all we know that the fallen angels, who must have shape shifted to appear as men, went into women on earth to create the giants which were later wiped out by the flood during Noah's time.  Although the Bible doesn't say how the second batch of giants appeared on Earth, we know that the flood wiped out all living creatures so I would have to assume that the 2nd batch of giants were created the same way that the first ones were by more fallen angels going into women on Earth.  

As for the sons of giants, who were also gigantic, it would have been impossible for them to go into women on Earth who were much smaller than them which must mean that some of the giants born to the fallen angels and women on Earth had to be female giants who later mated with the male giants to create the sons of the giants and daughters of the giants as well although they are not mentioned in the Bible.
