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)?

Look at the following answer choices and determine which belongs in the both category. testable, can be disproven explains natural phenomena, has evidence to support it prediction, tentative, one or more scientists working together well established, many different scientists working independently, highly reliable
