Best Answer: The biggest reason was that Britain started the Industrial Revolution earlier than other countries. Because they had newer technology, they could sell it to other countries to make money, and also use it to conquer other places.
1 Atopic dermatitis (AD) with Filaggrin (FLG) mutations is associated with an increased SC IL-1 cytokine profile; this profile is also seen in a murine homologue of filaggrin deficiency. 2  FLG mutations increase the risk for persistent dry skin, persistent eczema, and AE and non-AE at age 8 years. Loss-of-function mutations in the gene encoding FLG are linked with IV in Northern European and Japanese populations and results here demonstrate that FLG mutations are also associated with IV in a Bangladeshi population.
We often use these SNPs as genetic markers. Ancestral vs derived alleles. An ancestral allele or an ancestral trait (depending on whether you look at the phenotype or a t the genotype) is the trait/allele that was carried by the common ancestor of the taxon you consider. Single-Nucleotide-Polymorphism (SNP) is a kind of genetic variation that you find in population. This genetic variation is defined as a variation caused by only one single nucleotide (as its name indicates it).
