Question

Can someone tell me how to solve for this?

b 6 ın Neurospora, an Iris strain makes big as well asgroen colored colomes (gen type bg). It is crossed to a wild-type strain, which makes small and orange-colored colonies (genotype:+ +).The following ordered tetrads of asci were found, with the numbers of each type indicated below each tetrad. VI bg bg VI b g b+ b g bg bg b+ + g Calolate the map distanes h ge be cvbien ocledy 1od 45 m.u. between b and CM and 20 m.u. between g and CM B) 10 m.u. between b and CM and 40 m.u. between g and CM C) 5 m.u. between g and CM and 20 m.u. between b and CM D) 10 m.u. between g and CM and 40 m.u. between g and CM E) 7.5 m.u. between b and CM and 30 m.u. between g and CM 7.
