Segregation of markers in crosses to detect recombination within MAT

Cross	Ratio of progeny with the following genotypes:
Cross	MAT-1/ MAT-2^*	phleo^r/ phleo^s^†	hyg^s/ hyg^{r_^†}	phleo^r, hyg^r/ phleo^s, hyg^s^‡
1	24/25	24/25	24/25	6/18,400
2	23/26	23/26	23/26	7/18,400
3	26/24	26/24	26/24	10/17,800
4	35/15	35/15	35/15	11/17,400
Total	108/90	108/90	108/90	34/72,000

The genotypes of the progeny were determined by performing mating tests with wild-type strains 4857-4 and 4857-5.

^† Two hundred random progeny were tested for resistance to phleomycin (phleo^r) or hygromycin B (hyg^r).

^‡ For each cross, 20, 000 progeny were inoculated onto culture medium. An average viability of ∼90% was obtained for each cross. A total of 72,000 viable progeny were tested for resistance to both antibiotics. A second trial identified 36 progeny (out of 70,420) that were resistant to both antibiotics.
