Mainland-Dwarf Cross Mixtures

Sorry I missed this before. The female's size has a more dramatic impact on the size of the offspring. I'm not sure if it is because mtDNA is what is mainly responsible for size or what. Garrett Hartle (Reach Out Reptiles) has done some videos where he shows 63/37 crosses that compare when the mom is SD vs the male is SD at the same ages and it's astounding. As far as exactly how it works, I'm not certain, if it is 100% mtDNA based, then it shouldn't matter at all how much the father has, but since we know 1.0 mainland x 0.1 SD produces something close to SD but a little bigger, it's likely to be a combination of mtDNA and normal DNA.




Correct.

25% D x 25% D = 25% D, and any combo where the male and female share the same percent, the OS will also be that same percent, so 50% D x 50% D = 50% D, 75% D x 75% D = 75% D and so on.

50% x 25% = 37.5%
75% x 50% = 62.5%
75% x 25% = 50%

In the hobby, the norm is to call anything 50% or more Dwarf (or Super Dwarf) but still not pure D/SD. 25% D/SD is not technically a D/SD, but you can still list the percentages.

many thanks for this detailed answer! i suspected this but was hoping i was wrong - i would say however, specific to burms, i am going to be starting a size comparison thread between my dwarf female (75M/25D) and the mainland female i hope to get soon - my theory is that dwarf DNA is more significant in Burms than Retics but it will be interesting to see the results
