  1. Breeding Bunnies Procedure Guide 1st generation

  2. Have data table ready Place 50 (Ff) heterozygous bunnies in the Meadow Bag 50 “F” red beans 50 “f” white beans Prepare Genotype cups for bunnies born in next generation Have the graveyard ready… will NOT need until the end of the generation Set up model breeding environment FF Ff ff

  3. Draw 2 alleles out at a time  bunny born • Without looking at the beans, select 2 beans at a time, • Determine the baby bunny’s genotype • FF (Red Red) • Ff (Red White) • Or ff (White White) • record a tally mark in the • Put the bunny beans in the appropriate genotype cup FF Ff ff or or

  4. Repeat until bag empty  complete generation • Without looking at the beans, select 2 beans at a time, • Determine the baby bunny’s genotype • FF (Red Red) • Ff (Red White) • Or ff (White White) • record a tally mark in the • Put the bunny beans in the appropriate genotype cup FF Ff ff or or

  5. The cold of winter sets in…. • The ff bunnies are born furless. The cold weather kills them before they reach reproductive age, so they can NOT pass on their genes. • Place the beans from the ff container in the bunny graveyard before beginning the next generation (round). ff Bunny Grave Yard

  6. Count the SURVIVING f alleles (white beans) Ff Furry bunnies That Carry the Lethal “f” allele • Count the number of “f” allele (white beans) in the heterozygous genotype cup • Record

  7. To begin Generation 2 • Place all the surviving bunny alleles in the “meadow” bag to breed the next generation. “Meadow” FF Ff

  8. Repeat previous steps to breed generation 2-8
