these are some nice locks, i hope you will get nice hatchlings


about spider x spider, well, if the super form is lethal, it obviously wont hatch. if its mysteriously absent, what does that mean, other than it obviously doesnt hatch.

i think spider to spider is perfectly fine, if you can live with 33% non-spiders and 66% spider combos and a 25% drop in the number of eggs. i mean, you would expect 25% non-spiders, 50% spiders, and 25% nothing / undefined. but since you dont get the mysteriously absent super spider, it comes down to 33% normals and 66% spiders. thats what you get when you cross out a box in a 2x2 punnett square. and all sexually reproducing species with a diploid set of chromosomes are basically the same, the same is going on in most species, including humans.

if you use ultrasound to count the amount of tiny unfertilized follicles, and compare that to the amount of fully formed eggs you later get in the clutch, is it a match? or are there more follicles than turn into fully formed eggs? i mean, in general, in any breeding. maybe you dont even get a drop in fertility, maybe some other process saves the day.

either way, the stakes seem low, no animals are harmed. worst case is that some people decide to go for these pairings to get lots of spider combos in a clutch, even if it means that the incubator is a little bit less full. no harm is being done. you surely can get some nice clutches that way.
