In Neurospora , the cross was made : a,B x A,b . 1000 asci are obtained: a) Fill in the table above with the segregation pattern for the A and B

In Neurospora, the cross was made : a,B x A,b.  1000 asci are obtained:

a) Fill in the table above with the segregation pattern for the A and B genes

b) Are genes linked or unlinked? (Tell me how I can know about whether it's linked or unlinked)

c) Calculate all the possible relevant map distances

d) draw a map ( you may also indicate the arrangement of linkage of the gene A & B )
