Breeding Bunnies Procedure Guide 1 st generation

Set up model breeding environment 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 FFFfff

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 FfFFff or

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 FfFFff or

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

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

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

Repeat previous steps to breed generation 2-8
