Hiyah! ^^ So I was surfing the interwebs, and I found a picture of what is known as a 'Somatic Labrador Retriever' . And it got me wondering if lions could get it. After an exhaustive search O.O I was able to turn up three pictures of the same lion at different ages, and here they are; Somatic lion cub As an adolecent Same somatic lion as an adult What is Somaticism? Somaticism is a mutation that occurs during fetal development. It is different from chimerism as it simply 'turns off' genes in random areas, while Chimeras posses two or more different strains of DNA on the cellular level. Color genes stack (crash course in dog genetics), and with somaticism these stacks get removed, so there is a hole of sorts, resulting in the bottom gene showing through (black). What makes this a mutation, and not a Marking? Somaticism is a true deformation, incapable of passing through to an animal's offspring, or being bred (unlike albinism, overbite, and stork bites). Somaticism would be a rarer color mutation, and probably cover more than just a lion's leg. Sadly, this lion I have as an example is possibly the only somatic lion. But when one looks at a somatic lab, you could get a good idea of how many splotches would come through. Other examples of Somatic animals; .adult horse Posted Supports; 32 Support? Yea or nay? Anything you would change? |

Question about this because I haven't seen it. Could a melanistic animal Produce a somatic offspring If bred to a recessive melanistic animal? Like tortieshell cats? Cause this does look a bit like tortie... Only not. Like a weird co-dominant effect. Only this is seen on both male and female animals, unlike tortieshell. 0 players like this post! Like? |

No: Tortoiseshell is X inactivation, which is essentially a form of somatic mutation. Black cats aren't melanistic, either. Somatic mutation isn't in the least bit heritable, hence why the lion with the somatic mutation was partially black despite melanistic lions not existing, and also why he didn't pass on the trait to any of his offspring. The black shown on his paw wasn't even technically melanism, it's similar to how it works on the dogs - that patch of black just didn't have the genes activated to turn the black fur gold. TL;DR: Somatic mutation isn't affected by inherited genetics, so the parents that produce it don't really have an effect on whether or not the offspring is a mutant. EDIT: To expand on this. Theoretically, in a species where melanism is a dominant gene, a melanistic parent and a normal parent could produce a chimera with melanism on one part, and no melanism on the other, but, to my knowledge, all big cats have melanism as a recessive trait. Theoretically still possible with two carrier parents, but much less likely, not that there's a high probability of something like this occurring, in the first place. 0 players like this post!
