By definition, a clone is an organism or cell, or group of organisms or cells, produced asexually from one ancestor or stock, to which they are genetically identical. Madelyne is a clone of Jean; Stryfe is a clone of Cable. Most other characters where they say ‘clone’ are actually created by genetic manipulation.
Being someone’s relative means having enough genetics to have similar physicalities, psychological profiles, personalities. So you are a product of your parents be it natural birth or otherwise engineered (i.e., in vitro fertilization is an example of this, and so would be being fully grown in a lab). Nate Grey/X-Man is a ‘son’ of Jean and Scott; Adam is a ‘son’ of Katherine and D’Ken.
Here’s where I’m a stickler with the science (and sorry to be a killyjoy lol): having some sequences of someone’s DNA grafted onto yours doesn’t make you related or a sibling. If you get a kidney from a non-relative, you’ve received that organ for some function and that kidney will still retain its donor DNA structure – but it doesn’t make you related to the donor. Even more so if you receive a bone marrow transplant; that marrow is the progenitor for new blood cells which will permeate throughout your body and may affect the genetics in other organs in your body (and make you a genetic chimera of sorts) but again you are not related to the donor (in fact 23andme won’t allow you to use their services if you’ve had a bone marrow transplant specifically because it will give you false familial info).
The current ‘main’ Sinister is a clone of Sinister with Thunderbird’s X-gene introduced (from inception) to ‘make’ him a mutant; Warpath, and John Proudstar if he’s back, are not embracing Sinister as a brother. Sinister grafted Havok’s x-gene sequences onto the Living Monolith to enable Abdol to absorb ambient cosmic energy; the Living Monolith is not a Summers relative. If Spider-Girl has certain x-sequences from Scott to grant her eye beams, he’s a donor yes, but they're not related (she’s essentially Gwen Stacy with additional genetic sequences added in). That’s also how I saw Gambit in the X-Men: The End run – in that reality, Sinister was trying to create a mutant ‘clone’ of himself by introducing Scott’s x-gene (much how he used Thunderbird’s in the 616-reality). Even if that Gambit was fully created as half of Sinister's DNA and half of Scott’s DNA, then if we’re going to get technical Scott would be Gambit’s father not brother.
