YES NO</p><p>Explain why or why not? ______</p><p>MAKE A CROSS BETWEEN</p><p>Cross a PURE STRAIGHT TAILED MOM with a HYBRID CURLY TAILED DAD</p><p>What is the probability the offspring will:</p><p>Have Curly tails: _____ out of 4 OR _____%</p><p>Have Straight tails: ______out of 4 OR _____%</p><p>Be hybrids: _____ out of 4 OR _____%</p><p>Be homozygous: _____ out of 4 OR _____%</p><p>MAKE A CROSS BETWEEN TWO REEBOPS THAT ARE HETEROZYGOUS FOR EYE GENES.</p><p>PROBABILITY GENOTYPE PHENOTYPE</p><p>____ out of 4 OR ______% will be ______</p><p>____ out of 4 OR ______% will be ______</p><p>____ out of 4 OR ______% will be ______</p><p>What is the probability that the offspring from this cross will be able to see? ______% You are given a Reebop WITH EYES that can see. You would like to start a Reebop ranch and breed this Reebop to populate your ranch, however having blind Reebops is an added expense because they can’t find food on their own and you will need to hire more Reebop wranglers to watch them. </p><p>What could you do to find out whether this Reebop is EE or Ee ? ______Spring is in the air and it’s time for Reebop mating season!</p><p>1. Combine your Reebop’s genotypes with a partner’s genotypes in the Punnett Squares below:</p><p>Body Segments: Eyes: Wings:</p><p>Tail: Antenna: Legs:</p><p>2. How to determine your offspring’s traits: Flip a coin twice to determine which genotype your offspring will have. Based on your coin flips, the genotype(s) of your offspring will be in the corresponding square numbers.</p><p> Heads, then tails= SQUARE #1  Tails, then heads= SQUARE #2 1 2  Heads, then heads= SQUARE #3  Tails, then tails= SQUARE #4 3 4</p><p>3. The GENOTYPES for your Reebop OFFSPRING are:</p><p>Body Segments:____ Antenna:____ Tail:_____ Wings:____ Eyes:____ Legs:____</p><p>4.
