It is required to calculate the exchange value, and only two pairs of linked genes can be considered at this time.

According to the genotype of the egg in the figure, Rr and Ee genes are located on a pair of homologous chromosomes, and the egg in the figure belongs to recombinant type, so the genome of the biological oocyte becomes Re∨Re.

REd accounts for 7%, so re accounts for 14%, so it can be determined that the eggs that can be produced by the organism with RrEe genotype are: RE: Re: Re = 36%: 36%:14%:14%, in which Re and Re belong to recombinant type, so it can be determined that the exchange value = 650.

Therefore, choose: B.
