Genotype proves to be an important factor affecting the retention of sexual responsiveness following castration. Male F1 hybrids between C57BL/6 females and DBA/2 males (B6D2F1) show very prolonged retention. Experiment 1 used a diallelic design using C57BL/6, DBA/2 and BALB/c strains and showed that heterosis per se is not an adequate explanation of the superior retention of the B6D2F1 genotype. Experiment 2 showed that neonatal injections of 100 mug TP to B6D2F1 male mice did not result in… CONTINUE READING
