CemDeck is a non-combustible structural fiber cement board, designed and manufactured for use in fire-rated decking assemblies. CemDeck is non-combustible per ASTM E136, with up to 2 hour fire-rated floor assemblies. This specialist cement board also provides excellent load bearing performance, with UL listed floor assemblies. An interlocking tongue-and-groove edge ensures solid joining and uniform loading across supports.
If I get the question right, the answer is 6.25%, not 25% as the other answer says. Its easy to calculate. Siblings share 50% of DNA on average, it also doesn't deviate much from it as the shared HIR (half identical regions) are very long and can sometimes cover the whole chromosome. There are also the least amount of recombinations within one generation. Half siblings have half of that, as the name says, so 25%.
Like you, your siblings inherited 23 chromosomes from each of your parents. But because of DNA swapping, their chromosomes have a different combination of genes than yours. Yet on average, half of the genes are still the same.
