The diagram shows a Punnett square made to predict the earlobe shape of the offspring of two parents. The capital A stands for t
he trait of free-hanging earlobes, and the lowercase a stands for the trait of attached earlobes. Write the genotype of each offspring. What will be the phenotype of each offspring? Is the trait of free-hanging earlobes dominant or recessive? What is the expected ratio of free-hanging earlobes to attached earlobes in the offspring? \
