The heterozygous plant, for two independent assorting genes (P/p: Q/q) was selfed. The progeny that is resulted is as follows:
The progeny obtained to be:
88 P/- ; Q/- 25 p/p; Q/-
32 P/- ; q/q 14 p/p q/q
Thus, a total of 159 progeny that are approximately in the ratio of 9:3:3:1 (88:32:30:14) is resulted. This shows that the parents used in the study are heterozygous, for two independently assorting genes
