Chromosome VI Map
The top of the diagram represents the conventional left of the chromosome, and the bottom, the right. See below and VI Linkage data
for explanation.
Mitotic map
The vertical lines on the left of the map show mitotic mapping. Lines crossing a bold
vertical line indicate markers ordered relative to each other and the centromere by this
method. Selective markers are arrowed. Thinner vertical lines indicate markers
mitotically mapped distal to the selective markers, which are therfore not ordered
relative to each other by this method. The centromere is shown as a filled circle. Its
position to the left of lacA is unknown. Open boxes show markers located by
heterozygosity in translocation disomics to chromosome segments separated by the
translocation indicated. See Chromosome VI data for references.
Meiotic map
Vertical lines indicate links whose orientation has been determined relative
to neighbouring genes. For markers connected by
horizontal or diagonal lines, the distance is recorded, but orientation is not.
The main column of markers represents a backbone of loci which, except at telomeres
and in cases of well-established close linkage, have been mapped to at least one
adjacent locus on each side. It is usually, but not always, implied that three-point
crosses have been employed in such mapping. The number of bullets before and after
each locus denotes the number of linkages noted from the literature, to markers
respectively left and right of the locus.
Markers on the right hand side of the diagram are those less precisely mapped. In
many cases their positions have been related to markers in only one direction; in these
cases, or where one distance is markedly shorter than the other, only the distance to
the nearest marker is shown.
The three fol loci have been shown to be linked to each other, but not to other markers on VI.
See Linkage data for genes located to VI but not mapped further.
