ht1

• Allelic Composition: Lvs/Lvs⁺
• Genetic Background: involves: BALB/cByJ * C57BL/6J * FVB/N * SJL/J

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

reproductive system

teratozoospermia ( J:2977 )

♂ • mature spermatids are misshapen appearing short and wide rather than elongated with abnormal nuclei

male infertility ( J:2977 )

♂ • the majority of males are completely sterile

♂ • backcrossing for 2 generations onto a FVB/N or SJL/J background increased the penetrance of this phenotype to 100%

♂ • males resulting from backcrossing for 2 to 3 generations onto a C57BL/6 or BALB/cByJ background are fertile

cellular

teratozoospermia ( J:2977 )
