Answer:
yxz.
Step-by-step explanation:
Gene order may be defined as the correct arrangement of the gene according to the gene distance between them. The gene order can easily be calculated by looking the physical distance between the gene.
In the given question, the distance between xy = 6.9, xz= 0.7 and yz = 7.6. The gene yxz follows the order correct order at which the recombination distance of all the genes are satisfied.
Thus, the order is yxz.
