A tropical fish fancier produced an albino zebra fish (fish #1). This fish lacked the blue stripes characterisitics of a normal zebra fish. When he crossed a normal zebra fish (fish #2) with fish #1 all the offspring were normal. When he crossed two of the normal offspring (fish #3 and fish #4) 1/4 of the offspring were albino and 3/4 were normal. He then crossed an albino (fish #5) to fish #3 and 1/2 were normal and 1/2 were albino. What are the genotypes for all the numbered fish mentioned in this problem?
