WebStep 5: Gene linkage, recombination, and gene mapping. The last step is to understand why gene linkage is important in genetics. Gene linkage helps to know where genes were on … WebPrometaphase: Kinetochore fibers from opposite ends of the mitotic spindle attach to the kinetochores of the sister chromatids; the chrmosome moves toward midline. Metaphase: The centromere of the chromosome is aligned at the metaphase plate along with the centromeres of the other chromosomes.
