Genotype Ratio

The genotypic ratio is the depiction of the ratio of the resulting patterns and frequencies of inherited genes after crossing in the offspring of organisms. In simple language, it is the ratio of the composition of genes in the progenies of an organism. Genotype is the genetic constitution or expression of an organism. In simple language, the genotype is the type or combination of different genes in an organism resulting in some external appearance. Genotypic Ratio Genotypic Ratio Genes of an organism can be expressed (dominant) or remain suppressed without expression (recessive). The expressed genes result in the phenotypic characteristics of an organism. The particular phenotype can also have different genotypes. For eg., Tt and TT are different genotypes but express the same phenotype of tallness. Calculation of Genotypic Ratio The calculation of the ratio of genotypes for monohybrid, dihybrid, and trihybrid crosses is different. The basic steps of calculation are: Choosing the char

The Fifth Alternative

  The powerful character of the measure, however, leads some to object to non-co-operation because of that very reason. Striking as it does at the very root of Government in India, they fear that non-co-operation must lead to anarchy, and that the remedy is worse than the disease. This is an objection arising out of insufficient allowance for human nature. It is assumed that the British people will allow their connection with India to cease rather than remedy the wrongs for which we seek justice. If this assumption be correct, no doubt it must lead to separation and possibly also anarchy for a time. If the operatives in a factory have grievances, negotiations having failed, a strike would on a similar argument be never admissible. Unyielding obstinacy being presumed, it must end in the closing down of the factory and break up of the men.
