From: Experimental hybridization and backcrossing reveal forces of reproductive isolation in Microbotryum
Conjugation rates of experimentally-produced Microbotryum F1-hybrids with their backcrosses. Upper diagram shows observed conjugation rates for haploid isolates resulting from F1-hybrid type M-Sla1 × M-Sda2 and lower diagram from M-Sda1 × M-Sla2. All 25 haploid hybrid isolates have been backcrossed to parental isolates harboring the same species´ mating type (homospecific backcross) and to parental gametes harboring the different species´ mating type (heterospecific backcross).
