      A mouse breeder has a strain of black mice that normally breed true and produce only black mince. Occasionally, however, a brown mouse or two has appeared in litters of some of the mice.
      A) what do you hypothesize as the cause of the appearance of the brown coat color?
      a) both parents are heterozygous (not sure if thats right)
      B) If the brown mice are killed as soon as they are born, how many generations will it take to completely eliminate the bron gene?
      b) im completely lost, we just started this a few days ago. can someone shed some light on how i can figure this out? any imput in the right direction would be apperciated. thank you

      I think you also need to mention the type of dominance. For the second part, draw out some punnet squares.

      Since you can only eliminate the allele when you see it, and it’s recessive, could you actually eliminate it?

      has it occurred to you that you can’t eliminate it using above method?
