Four categories of polymorphism markers that can be used in genetic study in clonal F₁ populations. In category I or ABCD, each marker shows four identifiable alleles between the two clonal parents, represented by A, B, C, and D (see the four different colors in Figure 1). In the clonal population, four genotypes can be identified, represented by AC, AD, BC, and BD. In category II or A = B, one allele can be seen in the female parent and two alleles can be seen in male parent. In the clonal population, only two genotypes can be identified, represented by XC and XD, where X can be either A or B. In category III or C = D, two alleles can be seen in the female parent and one allele can be seen in male parent. The two identifiable genotypes in the clonal population are represented by AX and BX, where X can be either C or D. In category IV or AB = CD, both clonal parents show the same two heterozygous genotype. The two alleles in parents are represented by A and B, and three genotypes in their progenies are represented by AA, AB, and BB.
