Imagine that you are a new breeder for caique parrots. You can sell normal green-feather birds for $500 a bird. The mutation for blue feathers is rare and birds with this color can sell for $3000 a bird. Your goal is to produce as many blue feather offspring as you can, but you don't have the budget to buy blue feather birds as parents. Question: What genotype should you purchase for both parent birds to get the best chance of producing blue feather offspring? Create and use your Punnett square results as evidence to support your answer. You will need to make multiple Punnett Squares to see which parent genotypes make the most blue feathered offspring. Keep in mind that Green feathers (G) is dominant over blue feathers (g), so birds with blue feathers have the genotype gg. Some Punnett squares are provided for you to determine the possible crosses, but remember you cannot afford a blue feathered bird, so neither of your parent birds can have the genotype gg. Complete a Punnett Square for each possible cross and evaluate your results.
