vision/eye
• the majority of affected mice have the defect bilaterally
• of the mice affected unilaterally, significantly more have an abnormal left eye
|
• 70% of offspring from homozygous matings are affected with variable penetrance of the eye defect
• injecting a 15 day pregnant mouse carrying homozygous fetuses with 0.1ml of a 1.25mg cortisone acetate solution corrects the eye defect in all offspring
