- Read the following statements and find out the incorrect statements. (a). Though the genotypic ratios can be calculated using mathematical probability, by simply looking at the phenotype of recessive trait, it is not possible to know the genotypic composition. (b). The 1/4: 1/2: 1/4 ratio of TT: Tt: tt is mathematically condensable to form of the binomial expression (ax + by)2, that has the gametes bearing genes T and t in equal frequency of 1/2. (c). Based on his observation on dihybrid crosses Mendel proposed two rules that are called Principles or Laws of Inheritance: the First Law or Law of Dominance and the Second Law or Law of Segregation. (d). If in test cross, all the progenies shows dominant trait then the unknown parent is heterozygous dominant. (e). ABO blood groups are controlled by three alleles IA, IB and i. IA and IB produce a slightly different type of the sugar while allele i doesn’t produce any sugar.
