Chimerism is a whole lot of fun. Realistically, there are loads of humans with portions of their body differing pretty significantly in genes just due to somatic cell mutations during early development (not just standard zygote-fusing), right?
Sure, most of these changes would still be nearly imperceptible, but maybe some day whole-genome sequencing will be cheap enough that the true frequency of mosaicism can be studied by yoinking cells from all over one's body.
In the mean time, the intentional 'chimerization' of plants via grafting is pretty interesting too. Adam's Laburnum is a very visually striking example somewhat akin to this bird, https://en.wikipedia.org/wiki/%2B_Laburnocytisus_%27Adamii%2... sporting both yellow and coral-pink flowers, though the bilateral nature of the bird's mosaicism is what's really special.
There is a little evidence (10.1186/s12940-021-00729-8) that a very particular form of non-Hodjkins lymphoma is associated with glyphospate exposure (occupationally!), but ultimately... it's hard to say.
There's evidence of genotoxicity in human cell lines (10.1007/s13205-018-1464-z), but at possibly an unrealistic dose of glyphosphate-based herbicides. They are also demonstrably endocrine disruptors (10.1016/j.tox.2009.06.006), though again true in vivo exposure levels to glyphosphate is not well established it seems, so these studies are ultimately novel.
However, it's clear that they should be given more care than they are now. Hell, it took me like.. two months? to get a pesticide applicator certification and now I can roundup the hell out of anyone's crops, and I barely know anything about the stuff.
