Mitotic map

a. Mitotic recombination, methG, pyroA selective markers ; reference 332
b. Mitotic recombination, suCadE and pA (chromosome V) selective markers; reference 338
c. Heterozygosity in T1(IV;VIII) disomics; reference 337
d. Mitotic recombination using ectopically inserted [yA+ argB+] as selective marker; reference 5

Meiotic map

First markers are ordered from conventional left to right along each chromosome. Note that the ranking of markers not mapped to close neighbours may be quite speculative. The second marker is one determined to be to the right of the first marker (except where the map distance is given in square brackets [ ]: see below). Second markers are listed in order of increasing recombination value from the first marker, with the exception of unorientated linkages, which are placed first.

Where the map distance is given in square brackets [ ] the orientation of the linkage has not been determined.
"50%" linkage implies that markers were meiotically unlinked, but orientation has been determined by linkage to other markers.
">50%" implies that markers were meiotically unlinked, but orientation has been ascertained by mitotic recombination.
Linkage given as "?" indicates marker position ascertained relative to neighbouring markers, but distance not estimated.

Meiotically unmapped markers located on IV only by haploidisation or hybridization:
aloC, clA, ctsA, estA, galC?, galH, glrB, hygB, nimL, pacA, sfdA, sgpE, shoA, sudB, sumC, tguC.

a map distance likely to be distorted by heterozygosity for chromosome aberration.
