Recombination is an integral part of the pairing of homologous chromosomes. It occurs between non-sister chromatids during the pachytene stage of meiosis I (the first stage of meiosis) and possibly before, when the homologous chromosomes are aligned in zygotene (Fig. 8.3).
Recombination can occur between any two genes on a chromosome, the amount of crossing over is a function of how close the genes are to each other on the chromosome. If two genes are far apart, for example at opposite ends of the chromosome, crossover and non-crossover events will occur in equal frequency.or this experiment, a total of 2335 gametes were analyzed, and 303 (151 pr+ vg+ + 154 pr vg) of these were the result of recombination. The estimate of the linkage distance between pr and vg from these experiments is 13.0 cM [(303/2335)*100].
