Rates of instability and types of alterations for the microsatellite sequences in parental and recombinant spores

Genotype of spores	Rate of tract instability	Number of spores with additions or deletions of base pairs				Total
		−2	0	+2	+4
Parental	1.3 × 10−2	0	75	1	0	76
Recombinant	7.7 × 10−2	0	48*	3	1	52

Recombinant spores include crossing-over and conversion events encompassing the BstZ17I and/or AgeI restriction sites. The asterix indicates that four of the recombinants classified as microsatellite conversions could be mutants with alterations of the repetitive sequence: Three spores (−2) and one spore (+2).
