Mutation description

• Allele Type: Radiation induced
• Mutation: Inversion
• Oca2^p-25H involves 1 genes/genome features (Oca2) View all

Notes

p^25H, p-25 Harwell, recessive. This allele was neutron-irradiation-induced. Homozygotes are very similar to p^6H homozygotes, except that sperm morphology differs; p^25H homozygous males have a lower proportion of normal sperm (J:5219, J:5501, J:15082, J:5808). The sperm shows a loss of negative charge along the whole length of the tail (defined by the inability to stain with the positively charged colloidal iron hydroxide), suggesting that the defect in spermatogenesis may involve the Golgi apparatus and/or plasma membrane (J:11957). Females have reduced fertility. In addition, in p^25H homozygotes of both sexes, the pars nervosa of the pituitary contains degenerating nerve axons (J:5508), and the hypothalamus has reduced binding capacity for estradiol-17 (J:5219). Mutant females can generally produce a small, first litter, but the pups often die neonatally due to poor maternal behavior, which may involve improper nesting (J:49046).
