Abstract
Summary. Sexual development was studied in 25 hermaphrodite mice with the genotype Tl6H/XSxr. The majority of the animals had a male phenotype similar to that seen in XXSxr males. A few, however, had feminized external genitalia and were classified as females. Examination of the gonads and reproductive tracts of the male hermaphrodites revealed a strong tendency for the left gonad to be more masculine than the right. Most of the gonads in male and female hermaphrodites appeared to be ovaries or testes rather than ovotestes.
