[QUOTE="Herefords.US, post: 574406, member: 3972"] The key word is [b]absolutely[/b], HS. Think about it, if the selection process was absolute, then all results would be genetically identical. I was sharing this genetic discussion with our "coffee group" this morning. In that group is a math professor whose specialty is probability and statistics, as well as a couple of biologists. That discussion clarified my thoughts and I believe I'm correct. All the caveats must be considered. While the law of averages certainly has a bearing on what genes are carried forward, there are a number of genes where homozygosity exists, so it doesn't matter what ancestor(s) contributes them. In a totally random selection process, the law of averages would also typically tend to balance out any variations....BUT where breeding selections are made based on phenotype and perfomance, that process tends to skew the probability(law of averages), particularly genes in those areas being selected for. In a linebreeding program, it's really not important that the "blood" percentages are correct...or even close. It's far more important that the desired genes are the ones that's carried forward and homozygosity(whether dominant or recessive) is achieved. George [/QUOTE]
