  1. 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.
  2. You are studying a gene that controls ossicone (horn) length in giraffes. The wild-type long-ossicone allele (L) is dominant to the mutant short-ossicone (l) allele. However the L allele is only 60% penetrant. You cross two heterozygous giraffes. What phenotypic progeny classes do you expect and at what frequencies (assume the penetrance of L applies equally to both homozygotes and heterozygotes).
