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...
