Effect of mir-977 on male fitness components. a Male fertility. Total male fertility is depicted in the left panel. mir-977 KO have significantly higher fertility compared to the control. On the right panel, we present ovulation stimulation ability (top graph) and sperm quality (bottom). mir-977 KO results in significantly higher ovulation stimulation ability and a slight decrease (but not significant) in sperm quality. Student’s t test P values: *: P < 0.05; **: P < 0.01. b Meiotic drive. mir-977 KO leads to small and statistically insignificant X-chromosome distortion compared to control (Student’s t test P > 0.1). c Male viability. mir-977 KO results in a significant improvement in male viability. Binomial test P values: *: P < 0.05. d Mating success. The left panel depicts male mating ability, the right – reduction in female receptivity to subsequent mating. mir-977 KO results in no changes in mating ability but a significant advantage in reducing female receptivity compared to control males (Chi-square test P = 0.03)
