I’m certainly not @t_h_wyman, and I do hope he has a chance to jump into this, but I can shine a bit of light on this point. It’s one of the most commonly confusing things about reptile parthenogenesis. Partho offspring are not necessarily identical in appearance to the dam. They will not express any alleles which aren’t present in the dam (of course), but alleles which the dam carries as hets may be homozygous in the offspring, thus visually expressed. Here is one discussion on this for anyone who wants more depth.
