Some mice are born with a yellow coat controlled by the gene Y. Examine the setup and outcome of the following crosses, which produce two generations: Po : yellow mouse X gray mouse F1 :5 yellow mice, 4 gray mice P: yellow mouse from F1 X yellow mouse from F1 F2: 7 gray mice, 15 yellow mice with 9 dead Analyze the information provided to answer these questions: • What type of cross is the first cross? • Which trait is dominant? • What is the genotype of the yellow mouse in the first cross? • What is the genotype of the gray mouse in the second cross? • Why are 9 mice dead in F2?
