This study reports that the sex-determining factor is the transcription factor ZFY. The claims were later shown to be erroneous and the sex-determining factor was identified as the transcription factor SRY (https://www.ncbi.nlm.nih.gov/pubmed/1695712). Expressing SRY in the XX mouse "Randy" made it develop as a phenotypic male (https://www.ncbi.nlm.nih.gov/pubmed/2030730), confirming that SRY is indeed the sex-determining factor. A historical summary of the events was published 25 years after the birth of Randy (https://www.ncbi.nlm.nih.gov/pubmed/27190031).
