Genetic Diversity in a Collection

[Pythonfriend]

By inbreeding, you can concentrate that gene within your population, identify which animals carry the gene, and eliminate them from your population. You then take the healthy surviving animals, continue to breed them to relatives (not necessarily close relatives), and again eliminate those animals carrying the gene. Continue until you have essentially eliminated that deleterious trait, and now you have a healthy line of linebred or inbred animals.

thats most certainly not being done with BPs.

it means that you start breeding different independent lines, for example 5, and inbreed these 5 lines independent from each other. if you get one defect in one of the lines, you scrap the entire line. meaning the parents, the siblings, the grandparents, everything, the whole line is tossed. and you split the best of the remaining lines, so that you again have 5 lines. for this process, inbreeding is maximized. for the first 10 or 20 generations, you dont get any benefits, you will only be splitting and discarding lines. you will come across all kinds of defects and problems, and each of these is dealt with by discarding the entire line. over time, defects and problems will occur less often, and maybe after around 50 generation you have your final product: a highly inbred, highly homozygous, yet relatively healthy line. they all look the same, and one single outbreeding will ruin everything. unless you want to start completely from scratch, the only way to change the genetics of the line without losing it is now genetic engineering.

last time i checked, in BP breeding, people like to add new morphs into their collection. if you want to use inbreeding to "clean" the genome, thats not possible. the first step is to completely seperate your founding stock from the general population of BPs. you could do it, for example, with super pastels. but it takes decades, and all benefits are lost as soon as you breed any of them to anything else. but the only benefit (apart from being useful in genetic engineering and genetic research) is that you have a bunch of super pastels that you can now inbreed without running into random defects and issues.

attempts to do it in order to produce pretty pets are not going well, at least not in the case of dogs:
