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. In the problem above, map distance between locus b and locus g is: A) 15 m.u B) 25 m.u. 17 m.u )loci are unlinked 6en E) 33 m.u. 8. Three genes of corn, R, D, and Y, lie on chromosome 9. The map of the three genes, using map units is as follows: In a testcross of a trihybrid plant (R D Y/r d y) arising from truc-breeding RD YR D Y and r d yir d y parents, how many R dYi-d plants would be obtained in a progeny of 1000 if there were no A) 5 10 15 D) 20 E) 30 plants would be 9 For the problem above, assuming interference of70%, how many RDY/ obtained among that progeny? A) 30 B) 300 C) 700 353 10. A com plant known to be hybrid for three linked genes is testcrossed. The testcross progeny
