Question

An individual heterozygous for four genes, A/a • B/b •
C/c • D/d, is testcrossed with a/a • b/b • c/c • d/d, and 1000
progeny are classified by the gametic contribution of
the heterozygous parent as follows:
a • B • C • D 42
A • b • c • d 43
A • B • C • d 140
a • b • c • D 145
a • B • c • D 6
A • b • C • d 9
A • B • c • d 305
a • b • C • D 310
a. Which genes are linked?
b. If two pure-breeding lines had been crossed to
produce the heterozygous individual, what would their
genotypes have been?
c. Draw a linkage map of the linked genes, showing the
order and the distances in map units.
d. Calculate an interference value, if appropriate
