phenotype observed in females
phenotype observed in males
N normal phenotype
growth/size/body
• small but significant decrease in male body weight at 6 weeks of age but not at 4 months of age or in females

hematopoietic system
• osteoclast surfaces are increased in the lumbar spine
• osteoclast numbers are increased in the lumbar spine

immune system
• osteoclast surfaces are increased in the lumbar spine
• osteoclast numbers are increased in the lumbar spine

skeleton
• osteoclast surfaces are increased in the lumbar spine
• osteoclast numbers are increased in the lumbar spine
• both the inner medullary radius and endosteal circumference are smaller in males at 4 months of age resulting in a decreased medullary area
• however, morphology of growth plate is normal and no atypical skeletal malformations are seen at 6 weeks or 4 months of life
• mid-shaft femurs of males show an increase in cortical thickness at 4 months of age
• 4-month-old males show an elevated yield load (yield force) in a femoral three-point bending structural mechanical test

limbs/digits/tail
• both the inner medullary radius and endosteal circumference are smaller in males at 4 months of age resulting in a decreased medullary area
• however, morphology of growth plate is normal and no atypical skeletal malformations are seen at 6 weeks or 4 months of life
