Description

This inbred segregating mutant strain carries the atrichosis (at) and eye blebs (Grip1^eb) spontaneous mutations in repulsion and is homozygous for dilute (Myo5a^d).

Detailed description

Mice homozygous for the atrichosis spontaneous mutation (at) are characterized by sparsely distributed hair, especially on the trunk. The amount of hair varies, but affected mice can be easily recognized at 8 to 10 days old. Both sexes are sterile and have very small gonads with few germ cells. There is a great deficiency of primary spermatogonia in the testes. A quantitative study of maturation of ovarian oocytes showed that the proportion of resident oocytes recruited into the first wave of growth was much higher than in phenotypically normal heterozygous controls (J.J. Eppig, personal communication). This strain is also segregating for the eye blebs spontaneous mutation (Grip1^eb).

Development

Embryos produced by sib matings of males heterozygous for at and Grip1^eb to females that were either heterozygous or wild-type for at and Grip1^eb were cryopreserved in 2006.
