  4. In an organism, tall phenotype is dominant over recessive dwarf phenotype and the alleles are designated as T and t, respectively. Upon crossing two different individuals, total 250 offsprings were obtained, out of which 124 displayed tall phenotype and rest were dwarf Thus, the genotype of the parents were
