How is sex determined in these salamanders?

3. In certain salamanders, the sex of a genetic female can be altered, making her into a functional male; these salamanders are called sex-reversed males. When a sex-reversed male is mated with a normal female, approximately 2/3 of the offspring are female and 1/3 are male. How is sex determined in these salamanders? Explain the results of this cross.How is sex determined in these salamanders?Through heredity, alleles. You have to do a monohybrid cross and then say how many of what comes up. Cross Ss and SS. I am pretty sure the sex-reversed gene would be recessive.
