A possible concise summary is:
The video is about a snake breeder who cuts open the eggs of a clutch from two albino bull snakes. She expects to get some snow morphs, which are white, but instead she finds a normal colored baby among the albinos. She consults a snake expert who explains that the female snake might have retained sperm from a previous mating with a normal male, or that there might be other genes involved that affected the outcome. She learns something new about snake genetics and multiple paternity.

Some possible facts to extract from the text are:
- The text is about an experiment of cutting open snake eggs and observing the babies inside.
- The parents of the eggs are both albino bull snakes with some other genetic traits such as hypo and Whiteside.
- The goal of the experiment is to produce a snow morph, which is a white bull snake that has both albino and Whiteside genes.
- The text documents the process of cutting open each egg and describing the appearance and behavior of the baby snakes.
- The text reveals a surprising result: one of the eggs contains a normal-colored baby, which is not expected from an albino-to-albino pairing.
- The text consults an expert, Jeff, who explains some possible genetic explanations for this result, such as multiple paternity and sperm retention in female snakes.
