White "alien heads" in snakes after eggs are cut

[asplundii]

So my friend got 9 eggs from a ball python (probably retained sperm) ... The mother is a pastel and father is also. Does this means they are super pastel or something or are the babies underdeveloped?

Something you should consider is that the male has nothing to do with this equation and that instead of retained sperm what you have is a parthenogenesis event. And if that is the case, then you might see some developmental problems
