Fun with Genetics! Possible Outcomes Explained

[Art Geckos]

ツ This cross was put together today. Hoping to get some killer Enigma Trempers.



This cross can be broken down as follows [Note: Both also have Super Tangerine and High-Contrast; these behave as polygenetic traits, so we'll leave those out to simplify the problem]

♂ Tremper Het Eclipse x ♀ Enigma Tremper Het Eclipse

Genotype: ♂ ttEe x ♀ GgttEe

Because there are 3 hybrids (heterozygous traits), we can use this quick equation, to calculate the number of possible outcomes --> 2^n = # of possible outcomes, where n = the number of hybrids. Because there are 3 hybrids, we just plug in 3 for n, and get 2^3 = 2*2*2 = 8. Thus, there are 8 possible outcomes from this cross.

Possible Gametes: ♂ tE and te x ♀ GtE, Gte, gtE, and gte

Possible outcomes: ttGEE (Tremper Enigma)
ttGEe (Tremper Enigma Het Eclispe)
ttgEE (Tremper)
ttgEe (Tremper Het Eclipse)
ttGEe (Tremper Enigma Het Eclipse)
ttGee (Enigma Raptor, AKA: Nova)
ttgEe (Tremper Het Eclipse)
ttgee (Raptor)

Thus, 3/8 will be Tremper Enigma 66% Het Eclipse
3/8 will be Tremper 66% Het Eclipse
1/8 will be Raptor
1/8 will be Nova

And all of the offspring will have varying quality of Super Tangerine & High-Contrast markings. ツ

Thanks for breaking down the genetics and explaining the outcomes. You make it seem so simple! [emoji3]

Those geckos are gorgeous, btw, please keep this thread updated with the clutches and hatchlings. I can't wait to see how the babies turn out!
