When you are visiting the local pet store you start talking to them about their Ceti alpha-5 eel colony.  They tell you that some eels have red antennas, some have white antennas, and some have pink antennae. Whenever you cross an eel with red antennae to an eel with white antennae you only recover eels with pink antennae.    If you assume antennae color is under the control of one gene and you cross two eels with pink antennae what would you predict would be the genotypes and phenotypes of the progeny?
