Brown rabbits have the genotype BB or Bb. White rabbits have the genotype bb. If two brown rabbits, with the genotypes seen in the Punnett square above, have baby rabbits, what is the probability that the baby rabbits will also be brown? a) 25%
b)50%
c)75%
d)100%

​

Explanation:

BB: brown

Bb: brown

bb: white

Since you didn't give the variables, here is how you make a punnet square:

Make a box with four boxes inside.

|                |                |

|                |                |

|                |                |

Put the variables on each side:

Example:

Bb

B|                |                |

  |                |                |

b|                |                |

  |                |                |

then fill in :

Bb

B|         BB       |   Bb        |

  |                    |                |

b|                    |                |

  |        Bb        |   bb         |
