In the cell depicted below, chromosome #1 contains 2 genes we can track: ruhroh (which has
dominant [R] and recessive [r] alleles) and dangit (which has dominant [D] and recessive [d] alleles).
Chromosome #2 does not contain genes we are able to track (and thus has no letter labelling).
Follow the images of simulated meiosis II shown below and observe the crossing over event involving
the portion of chromosome #1 that contains the dangit gene. Write the genotype of the parent cell and
the genotypes of each of the four gametes.
