| Genetic information | B6/129 Spo11_beta_b_ki/+ is a knock-in hemizygous for the Spo11_bet_b splice isoform. It has been generated by knocking-in the Spo11_beta-b cDNA into the Spo11 locus, destroying the ATG in exon 1. |
| Phenotypic information | Homozygous:Unknown.Heterozygous:Healthy, most males are fertile beside increased missegregation of XY chromosomes. Frequency of XY asynapsis varies among mice from about 10% to 60%. Females are fully fertile. |
| Breeding history | Knock-in construct introduced in A9 ES cells (C57BL/6 and 129 background), then mutant mice crossed with Spo11+/- mice with mixed C57BL/6 and 129 backgrounds. |
