genes occur on chromosome , Biology

In Drosophila, these genes occur on chromosome 4.

H - wild type (normal)     h - hairy

F - wild type                   f - frizzled

E - wild type                  e - vestigial


The cross HFE  x  hfe   yielded the following:

    Hfe         hfe


HFE - 393    HFe - 28

h f e - 409   h f E- 30

H f e - 58    H f E -  1

h F E - 80    h F e -   1


a. (2 pts.)  Which group in the progeny represents double cross-overs?  Parental types?

b. (1 pt.)  What is the correct gene order?

c. (7 pts.)  Compute for the distance between genes and draw the linkage map.

d. (2 pts.)  Compute for coefficient of coincidence and interference.
