KREB Radio is meant to be a fun light-hearted take on very complex scientific issues. In this episode we focus on the inheritance of the X-gene in X-Men, the oddities of androgen insensitivity and what determines if someone is male or female for Olympic competitions, hormones, genetically-modified organisms, with molecular biology, biochemistry, wonderfully entertaining commercials, and small tidbits of 60 second science with Alex Generous.
