Tyrc-44H mutation (1 available); any Tyr mutation (376 available)
phenotype observed in females

N normal phenotype
pigmentation
• the coat is white except for traces of pigmented hair in the ano-genital region, noted only in older mice
• evident at birth allowing accurate classification of mice where Tyrc and Tyrc-44H are segregating
• at weaning homozygous mice have dark ruby eyes that intensify to nearly black by 3-4 months of age

vision/eye
• evident at birth allowing accurate classification of mice where Tyrc and Tyrc-44H are segregating
• at weaning homozygous mice have dark ruby eyes that intensify to nearly black by 3-4 months of age

integument
• the coat is white except for traces of pigmented hair in the ano-genital region, noted only in older mice
