You run a pet store. Many people have come in and bought blue parakeets. You want to save money so you are going to breed your existing parakeets to produce as many blue offspring as possible. You still have green, blue , yellow and white parakeets in stock. Assume the green , blue and yellow in stock are homozygous and heterozygous in genotype, so you have many choices. You select a heterozygous green male to be one member of the breeding pair, because he is very friendly to people. What color female would you select as his mate?
