hypomorphic allele - genetic evidence
lethal | recessive
male semi-sterile (with αTub84Bunspecified)
Transheteroallelic combinations produce males that are sterile or weakly fertile.
Expression of αTub85EβTub85D.PH partially rescues the defective αTub84B function in spermatogenesis: most spermatids have complete axonemes.
