Parthogenesis is not known to occur in BRB's but has been alluded to in other boa species. Mikes comment that all the unexpected visual morphs were female could lead down that path if all visual morphs were the same morph as mom. I honestly don't know if the babies match the mom's but I think they do
My bigger concern with prior DH litters having odd outcomes would be retained sperm. It's been seen over and over that prior year males sperm in BCI has fertilized current year ova resulting in morphs that should not have occurred. If that were to happen in a Hypo x Anery cross, the odd outcome morphs would be from that retained sperm but an even bigger concern and possible huge monkey wrench would be if the prior male was a het.
In 2006 Mike produced a litter of DH Ghosts using his Hypo male and an Anery female from Robert Seib. In that litter there were two Anery looking babies along with the normal ones. In 2009 Ken K produced a litter of DH's form Sarp Anery male and Lockwood Hypo Female, Also with an unexpected Visual female baby, this time a Hypo. Totally unexpected and I can only think of three possibilities:
1) Mikes Hypo male is het Anery and/or Ken's Anery male is het Hypo - Possible but unlikely and odds do not support the theory, not enough visual babies produced to support Het x visual pairing expected outcomes.
2) Parthogenesis - those two Anery babies and one Hypo baby are from the respective moms only and not fertilized by the associated males. Real possibility.
3) Retained sperm - Those three babies were actually sired by a prior year male. A real possibility??
Now for the kicker, IF #3 was the cause of the visual Anery and/or Hypo babies AND IF the prior year males were het for their respective traits (IMO VERY likely) THEN, some of the "normal" looking babies could have also been sired by the same het males. So those two litters of DH Ghosts might not all be DH Ghosts?? Ouch!!!
Again, this is all speculation, only thinking my way through the possibilities.
Would love for Ken, Mike and/or Robert to chime in with missing details (or to correct any errors I may have).
I did speak with Robert recently and he did not think he hit on the ghost in this years litters. Waiting for sheds to get a better look.
