Mutations,
alleles, and
phenotypes
All mutations/alleles(3) : Targeted(3)
 
Males homozygous for targeted null mutations produce small litters and exhibit incomplete chromatin condensation, sperm head abnormalities, and reduced sperm motility. Severity of the phenotype is influenced by genetic background.
 
Interactions
Tnp2 interacts with 34 markers (Mir1b, Mir17, Mir20b, ...)
