Pollination Tech needs makeover...

Ah, so you checked Chloe and she is homozygous for her alien skin? Then, if her breeding partner is also homozygous for his (un-binned) custom skin, their child has a 50% chance of showing either skin. However, that child is obviously going to be heterozygous, no matter what it shows, so things get a bit uncertain as you go on down the generations.
It does not work like that with the regular skintones, thus my question about the genetic dominance of the skintone/eyes.
If you have one sim with regular Maxis skin/eyes - whatever colour but homozygous - and you pair it with homozygous custom skin/eyes, you always get the custom for the child.
If you have one parent with heterozygous custom skin/eyes and one parent with homozygous regular skin/eyes, there is a chance of x percent (definitely less than 50) to get a child with regular Maxis skin (and custom eyes most likely). It's not quite like biology lesson, when we plagued the neighbourhood with our drosophila melanogaster breeds.
The alien eyes can't be 100 % dominant because I remember Pascal Curious (where I reloaded the game about a million times) giving birth to children with non-alien eyes (and did they look horrible!). I can not remember if they always had the alien skintone.

This is a dangerous statement that hasn't been universally true since the early days of the game. A lot of creators now geneticize their custom eyes and skins, so that customs aren't always dominant. All of my eyes and custom skins are geneticized, and only a handful were done by me.

Mentally add "non-geneticised" to my statement if you wish for more precision. I don't think any of the skintones or eyes I have were geneticised by the creators and I have not altered them.

This is not the same situation as Chloe and her mate which you asked about first. In her case, I first assumed she was heterozygous custom, and her mate, homozygous and custom.
How many times did you re-load the birth to determine that the percentage is less than 50 for the case you describe above? I've had slightly less than 20 2nd-gen alien births, but a quick chi-square test shows my results are within the expected variance. EAxis has claimed that it should be 50%, but they've been known to change the rules. ::)

I'm not sure about Pascal's genetic material, as I avoid Strangetown since I read in the War Room that most of its citizens have scrambled genes. Although it is possible that EAxis have changed (or borkened) the rules for alien genetics, I'm fairly confident that there isn't any way to change the dominance of alien traits. PT replacements follow the same rules for genetic inheritance as the default.

If I would use this one as a replacement, it would pass on the green XM Sims hair (if downloaded) or - if I don't have that hair - I would end up with an alien which has any of the custom hairstyles I have? Meaning that if I am unlucky I have an alien that passes on blond dreadlocks or some other custom hair that I have been too lazy to delete? Could I modify the file, so that it has black hair as default again?
Genetically he have the default alien skin and eyes and it will work how the game planned. I didnīt changed the dominance. If you not have the XMhair, the game will assign any other non-binned hair. Even with the hair in my game, I have offsprings generated with other customized hairs. I have a test family that had a blond girl and a red-hair boy. The next generation can have a default tone skin, just like regular generated abductions and default eyes, like Jill Smith from Strangetown.
Since is a default replacement, all genetics will follow Maxis default rules. None of them are dominant like a customized sim with customized skin, hair and eyes - these ones tend to be dominant to all others just because the makers never think about sims genetics when they make stuff, so bodyshop attributes the highest value.

I don't believe it is possible to make the PT's skin or eyes "less dominant". The PT has homozygous, un-binned custom alleles for skin and eyes, whether you use a default replacement or not.
It is possible when you make a default replacement, but this piece of info must go inside the skin, eye or hair that you are using as replacement.

If Chloe Singles isn't genetically borked
There is a thread here somewhere that explains that a lot of Strangetown sims are genetically broke. I checked some of them myself with Simpe, John and Jill Smith, as example, have no genetic data for skin and eyes. I never checked Chloe, but is possible that she have some segment missing.

I don't know if they were truly bred in-game, but from what I have seen, none of the Maxis sims carry the genetics of their parents. Chloe and Lola have alien genetics on both sides. It's like Lilith and Angela (they have genetically red hair despite Mary-Sue being black haired). I think the only one who carries the genetics of mother and father is Cassandra Goth.
Lilith and Angela actually are Mary Sue and Daniel offsprings. I tested the genetic data plus facial geometry and gave to Mary Sue and Daniel 2 new offsprings, both resembles Angela and Lilith, one have black hair and the other one red hair.
Cassandra and Alexander are not Bella and Mortimer genetic kids, they are template made (Alexander uses the same template as Goopy, Cassandra uses the same template as Kaylyn, the maid). Itīs impossible to make offsprings between Mortimer and Bella that remotely resembles Alexander or Cassandra. Also, Mortimer is genetically blond, he is not dark hair.

Exactly.
