Results of meiotic mapping from diploid strains

(a) BUT^S/BUT^R (BUT1-2) v ura3/GCN3::URA3			(b) BUT^S/BUT^R (BUT1-1) v ura3/GCN3::URA3
PD^a	TT^b	NPD^c	PD^a	TT^b	NPD^c

Diploid strains were constructed by crossing either (a) yMK1465 (BUT1-2 GCN3::URA3) and yMK39 (ura3) or (b) yMK53( BUT1-1 ura3) and yMK1475 (GCN3::URA3).

^aThe number of tetrads that are parental ditype (PD); i.e., if the parents are AB × ab then a PD tetrad pattern consists of two AB spores and two ab spores.

^bThe number of tetrads which are tetratype (TT), i.e., if the parents are AB × ab then a TT tetrad pattern consists of AB, ab, Ab and aB spores.

^cThe number of tetrads which are non-parental ditype (NPD), i.e., if the parents are AB × ab then a NPD tetrad pattern consists of two Ab spores and two aB spores.
