If you merge two horses, you can have the potential to get many more gene combinations, depending on parents if they are lined horses though

To my knowledge, chimerism only affects the colours of a horse, not their breeding or showing abilities. In this case, it is good to think of it as "two sires in one", but again, only in regards to colour. Usually each strand of DNA has a 50/50 chance of passing onto the foal. This means that the foal has equal chance of inheriting genes from strand one OR strand two. A foal cannot inherit one gene from one strand, and a different gene from another.

This is important because while Foundation brindles and the RGS is done equally (if you buy a gene, it goes on both strands) you can either get random chance genes (like cream on a horse from a HH that does not give a copy of cream) or you can gmt on "uneven" genes. Lined chimeras can also have "uneven" colour genetics, ie differences between strand 1 and strand 2. Let us use my boy Mocha here as an example.


Mocha In The Making

He has a lot going on, but the main differences are these:
Strand 1:
Agouti - a/a
Dun - ONX/D
Agouti Promoter - -/-
WF Minimal

Strand 2:
Agouti - A/a
Dun - ONX/nd1
Agouti promoter - +/-
WF Light

Showing off the examples of the inherited strands are these two full sisters. The first letter at a location is from the father/sire, the second letter is from the mother/dam.

2M Roster ImpactCapacity Sister 2 here inherited Strand 2 from her father. She has a copy of agouti (A), non dun 1 (nd1), and even got a copy of agouti promoter (+). She also inherited her fathers WF of light.

Some of your questions make me think you may not fully understand how chimerism works in the game. You can create or breed a chimeric horse or make one in the GMT lab. They are identical. There is no difference between the three different ways to get a chimera.

They are if you like them. You won't be successful in the game by trying to market your barn around what is "popular" having a large show herd is really the only way to do that.
