Question: The following tetrad data were obtained from the cross A B Ã a b in Neurospora: Use these data to construct a linkage map of

The following tetrad data were obtained from the cross A B × a b in Neurospora:

Spore Pairs Top of Bottom of Number of Ascus Ascus Tetrads (1,2) (3,4) (5,6) (7,8) AB AB ab ab 1766 AB aB Ab ab 220 AB A

Use these data to construct a linkage map of the two genes and the centromere on their chromosome.

Spore Pairs Top of Bottom of Number of Ascus Ascus Tetrads (1,2) (3,4) (5,6) (7,8) AB AB ab ab 1766 AB aB Ab ab 220 AB Ab ab 14 Total = 2000
