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.
Cross the mutant plant to wild type. If the F1 progeny phenotype is: i) wild type then the mutant allele is recessive (most common) ii) mutant then the mutant allele is dominant iii) between wild type and mutant then the mutant allele is co-dominant. Basic Genetic Analysis of Mutants 3.dentify the double mutant class in the F2 population by phenotype if possible. The identity of double mutants (genotype) can be verified by crossing to homozygous parents (test cross). Otherwise one may have to rely on the frequency in the F2 as proof of identity.
