Summary information of individual linkage groups in the intervariety cross between strains of serotypes A and D in C. neoformans

Linkage group	Corresponding chromosome in JEC21	No. of markers	Length (cM)	Physical distance covered by markers (kb)	Ratio between physical distance and genetic distance (kb/cM)
1	1	13	38.5	2135	55.45
2	2	9	12.5	1401	112.08
3	3	11	11.8	1604a	195.61b
4	4	11	32.3	1612	49.91

^aMarker CNC07180 was not included, because it was identified as a translocation (see results).

^bGenetic distance involving marker CNC07180 was not included (see reason above). Therefore, a genetic distance of 8.2, not 11.8, was used to calculate the ratio.

^cNot calculated, because markers in LG 8 were located on two different chromosomes in JEC21.
