In this diagram, the top chromosome is the wild-type chromosome, while the bottom one carries an inversion. The star is the centromere. A B C * D E F G A B F E D * C G 1. During meiosis recombination occurs between the centromere and the region marked "D". Draw out the recombinant gametes showing the gene order and position of the centromeres in each. 2. Are either of the recombinant gametes likely to give rise to viable...
