Dominant or Recessive?

thegentleman is correct in is assessment of the various traits with the exception of baldness. Baldness is NOT a sex linked trait but rather a sex influenced trait. It is a dominant characteristic influenced by the sex of eh individual. males need only one of the autosomal alleles to be bald. femals require two of the dominant alleles to go bald(yes women do but generally after menopause) Testosterone levels determine whether the charactersitic is expressed.
