Extended Data Fig. 5: DAPI staining of nucleus and sporulation efficiency for diploids.
From: Karyotype engineering by chromosome fusion leads to reproductive isolation in yeast
a, DAPI staining of nuclei in diploids. b, Sporulation efficiencies for 2n = 32, 2n = 16, 2n = 8 and 2n = 4 homotypic diploids. y-axis: percentage of asci that have 0–4 spores. x-axis: different diploid strains. Sporulation efficiency was measured after shifting diploid strains in the sporulation medium for 10 days in room temperature. c, Fractions of asci with 0–4 viable spores in heterotypic and homotypic crosses.
