During biology class, miss castelli showed an example of a dihybrid cross and crossed two traits. her favorite animals are sea turtles! she decided to cross the traits for shell color and pattern. sea turtles can have a green or brown shell and a square or circle pattern. green and square are dominant traits. a heterozygous green turtle with a circle shell pattern crosses with a homozygous dominant green turtle and heterozygous square shell pattern. what are the parental genotypes? now, you will complete a cross (hint: foil). list all potential genotypes. (g=green, g=brown and s=square, s=circle) what are the phenotypic probabilities (percentages for each phenotype)?
