Vedclass · Answer

(a) : Test cross is performed to determine the genotype of $F_2$ plant. In a typical test cross an organism showing dominant phenotype and whose genotype is to bedetermined is crossed with one that is homozygous recessive for the allele being investigated, instead of self&shy;crossing. The progenies of such a cross can easily be analysed to predict the genotype of the test organism. Given ahead is an illustration of test cross:
